I'd hope that they would allow a one-time name change along with a one-time race/gender change, in the event that they do offer it. Not everyone who wants a race/gender change has a name that will suit whatever race/gender they are hoping to change to.

For example, I don't think Fleur's name would be suited to a male Miq'ote, or even a female Highlander (and since it is MY character, it doesn't matter if someone else thinks it is fine, y'know?). And if Fleur was high ranked, I'd be annoyed if I had to either reroll or put up with a silly name, while my friend who has a more basic, unisex named Miq'ote could just gender-swap her or make her a Roegadyn with no problem.

Mind you, I don't plan on doing any race or gender switching myself, but I think it is important to consider. I do see the potential community issues, though I think we could deal with it for a one-time and potentially limited time offer that would greatly please many dedicated players.
