I'm not violently opposed, but I'm really not very sure of this name choice. Unless these names had any cultural heritage or significance, such as family names. For example: By naming your daughter after your cherished Aunt Tali or very much loved Great-Grandma Zora, it seems less like you are trying to make your own point with another human beings name and more like respect, adoration, and perhaps tradition (if you are into that kind of thing. Not everyone is and that's okay too.) Personally, I think Tali'Zorah seems like a stretch; and you have no other way to explain your decision.
Not only will you have to explain it to others, your daughter will eventually have to explain it's significance or origin to employers, etc, if asked where she came by the unusual name. They'll expect family/cultural heritage, not space aliens. How would you explain it to your own child when they ask the importance and significance of their name? Then again, adults and children will make fun of anything and everything. My name is Vanessa. There isn't much to make fun of as far as my name goes (or at least nothing they could come up with), so they tortured me about my appearance instead. However, if you are insistent; breaking up the name seems like a better compromise. Tali as the first (which I do find pleasant) and Zorah as the middle.
