With the exception of Jem and Sailor Moon I think that list would be somewhat counter productive to the stated purpose. Sailor Moon has the issue of being a comedy as well, something that a lot of people don't "get" is that it's supposed to also be a comedy, and part of the humor is how it's a bunch of girls doing these things, and how it looks.
I've done a lot of reading on, and research on Anime, and while there are a lot of strong female characters that are intended to be taken entirely seriously, Sailor Moon itself arguably can't be despite some attempts to get more serious in it's later days (so to speak).
On the bright side, I don't think you'd wind up upsetting Japan by casting a blonde haired caucasian girl in the role. To be entirely honest girls of all varieties, and blondes in paticular are considered kind of hot down there, and to be frank when she was created (even with a Japanese name) that was probably the offhanded intent.
According to other things I've read, when people ask "what ethnicity is this character" the answer is usually Japanese, however if a character looks like they should be from another Ethnicity (white, black, hispanic, etc...) chances are the similarity was intentional and that is how the character is being treated but the creator wanted to keep things Japan-O-Centric. There is apparently less focus on this, and a gradual shift towards having non-Japanese characters, so just coming out and casting some hot blonde Jailbait as Usagi
would probably work just fine, 10-15 years ago it probably wouldn't have.
I'm not sure if "She-Ra" would work, looking at the previous He-Man movies, and the simple fact that I've never been entirely sure that it was actually directed at girls. I can't think of many girls who got into "She-Ra", most of the people who watched it were guys in my experience who watched it as an extension of "He-Man".

If I had to look at characters to appeal to girls, with the intended messages here, I'd honestly look later on down the pipe. Simply put I think the 80s era (where most of this is from) was among the last generation with a more traditional focus in targeting gender roles. I don't think a lot of the classic charaters for girls from that time period would translate well into a real "girl power" movie, and what's more most of the concepts are silly enough where I don't think they would appeal to adults. I mean you can sort of sell Giant Robots beating the crud out of each other, because action appeals to all ages, and science fiction in general goes cross generational. I don't think a girl on the other hand is going to be all excited about "Strawberry Shortcake" baking stuff and then trying to protect it from "The Purple Pieman".
I think most of the good properties simply aren't quite old enough to be recycled for nostolgia factor yet.

As far as gender roles go, well I'm going to again be that "worst kind of person".
Right now I think one of the biggest problems with society is that gender equality, for all it's fairness, has lead to a situation where there is nobody around to raise or take care of the children. A lot of issues related to the youth, bad parenting, and similar things come from nobody being at home, or when someone is with both parents being so exhausted physically and mentally that they can't do the job "right".
Kids are increasingly being raised in daycare centers, or grow up as "latchkey kids" who spend a lot of time home alone, taking care of themselves, even at a relatively early age.
When it comes to isses like video games, dear to those here at The Escapist, people talk about parental responsibility, and I agree, but rarely look at why parents are failing so much today when it comes to reviewing material for their kids and so on. There are parents out there who have made things work despite both working, but it's not easy, and not everyone can do it. Parenting is one of those things that nobody can be fully prepared for, and luck always plays a factor as especially in today's job market people can't adjust their schedules around family, you either work the company's set time, or they replace you.
I don't believe women are mentally inferior to men, or anything of the sort. I do however believe women are naturally better at raising children, nestbuilding, and similar behaviors. Men and women are just wired differantly. Men CAN raise children, but women are better at it. Ideally of course both parents need to have a strong prescence.
Normally I would say that I think more women need to be encouraged to stay home and take care of children for societal reasons (and truthfully based on relative capabilities and the profitability of jobs, this could be reversed in some cases), as opposed to the current "run out and get a career, Grrrrl power" attitude you see expressed today. Unfortunatly we can't do this because the economy has adjusted to the idea of two income families, and most families without both adults working would be unable to meet the financial responsbilities.
I know lots of people are going to say this is sexist and mysogynistic, or whatever else. While not politically correct I don't think dismissing what I'm saying entirely is wise however.
We will probably find a way to make things work, and despite how it sounds I'm a big fan of equality, but right now I don't think someone can really consider pointing out the benefits of having one parent being a home maker to be a bad thing. What's more I think most people would generally agree that women tend to be far better at doing that kind of thing than guys are, even if it's not an absolute truth (as in certain pairings things can work out in the opposite fashion).
I very much thing dealing with this is one of the major obstacles facing society. Either we need to find some way to "turn back the clock" and make it practical and desirable for one parent to stay at home (without resulting to oppression), or the problems we're dealing with now are just going to get worse.
