I'm glad you think so since that's exactly the approach I've taken in both
the games mentioned, and only partly because it involves less drawing ;)
We discussed choosing ethnicity for the second game but the main
character's backstory is too rooted in their family history, especially
their father's family being Bengali. They're also always visibly disabled,
which again is a part of their backstory and affects how people relate to
them. Their variable gender and presentation affect how people react too,
if only in minor ways, but that's the kind of thing it's fun to vary in
multiple playthroughs of a dating sim, and is also pretty easy to keep
track of. Their body type isn't going to affect gameplay, it's just to help
players with the roleplaying aspect.
I don't think I've ever seen a game let you choose you character's
ethnicity and have it actually change anything in the game (not counting
being an elf etc). I can think of a few ways you might plausibly be able to
implement it but feel unqualified to decide which would be best.
