well, i'm not sure what plans you have for her in the long term, but there are very good usability reasons - for this community -  not to have multiple UVs.  the main benefit of the Unimesh was shared maps.  multiple UVs mean you have to switch characters just to use different textures on the same figure..  basically, you're making her more complex to use, without a clear benefit to the average user. 

about 99% of the time, it's better usability to offer one good choice than to force people to chose.

none of that matters if you don't want people to sell things for her, or for her to be used by a wide audience instead of just the kind of people to re-write cr2s.  otherwise, i'd suggest trying to make using her simpler wherever and whenever you can.
