While I agree that RTS blows on consoles, I do think it would be possible to make a decent one for the Wii. I think some of the gameplay mechanics would have to be retooled (i.e. current RTS incarnations would be unhappy ports - start from the ground up), and it might be best in the long run to consider developing (yet another) doo-dad add-on to clip into the Wiimote. But buying doo-dads for me is unfulfilling so far, and it's going to be a tough sell unless you practically give it away in the box. Besides the 'chuck and the controller clippies, there hasn't been a single new doo-dad for the Wii that I think is worth the money. (I don't have the WiiFit yet, it might be that the board is as nifty as they say.) So if one was to combine ideas - have a control wheel AND a new add-on that would act in place of a keyboard - then RTS might be a viable option. Also, while the buttons on the Wiimote are nowhere near as complex as keyboard options, the amount of fiddling one *can* do with all those buttons is staggering.

If I counted correctly, that's already 49 different control options. Even the 'chuck brings another control stick and two more buttons into play. Also, there be more ways than that to control a dude or group of dudes. Or dudette(s). Homies. Whatever.
Having a keyboard just makes all the controls easier to remember... well, if you're used to that kind of thing. I think the biggest sell Nintendo would have to face is making an add-on for the Wiimote more useful than *1* game... although plenty of 'tards (like me) are buying those silly steering wheel things. (They make it HARDER to drive! D8 )
(Nevermind that Mario-Wiikart cheats anyway... =P)
