First of all, thank you for that! Truly! BG3 inherited that horrible character generator from DOS and if Larian insists on using that abomination, the list they could do is to supply such comparison pictures. (Not going to happen, of course, but one can dream and meanwhile such handmade lists are very helpful).
I do not think the faces a too similar. Should they change them more, and it will be unplayable extremes (even now, like with halflings, there are only a couple (at best!) of acceptable faces per each race). But yes, no difference between the races at all. If they intend to keep it this way, maybe the best solution would be to unlock all faces for all races.
(My gripe with tieflings, though, remains - why only one type of horns?! Why?! It does not matter if they are long or short (or even cut off), they are of the same thickness at the base and in the same place! And after that Larians act surprised that people don't use all that "wonderful racial additions" and prefer humans! Of course, they do, because what's the point?)
Anyway. Yes, a lot of RPGs that allow you to roll your own protagonist also allow much more freedom of customization than BG3. Not all RPGs (!) mind you. But many. I doubt it is physically possible to introduce true shape-morphing into this character generator. But (!) there is a simple way - cosmetics and unlocks. Add lipstick and blush options (just a tattoo for specific areas, how difficult it can be?), unlock all options (faces, eyes, hairs) for every race, and we can get far superior character generator with practically what we already have.
