Problem is, you do that and then you're going to have a bunch of people asking to be recognized as X race, with racial bonuses and all that. Besides, if you turn your human green, with tusks and high muscle definition (as an example), would you still be considered a human at that point or just some weird, unidentified morph simply because Inno doesn't want to add them to the game? At that point the game may just say you're a lesser boar or elephant morph... meaning you'd have to use your imagination to do the rest.
I think it would make more sense for people to wait for the race/morph framework. Someone is definitely going to add all of those races with proper support and racial bonuses, which is better than a pretend, half-baked version.
Yeah, I get that.
It could be an optional solution tho.
Basically, those changes are only available to the player, and not on random NPCs (maybe on Kate's shop options too?).
So, it could be as only the player actually recognizes them as Orcs/Elves/etc, since it's our dimension lore (it could be assumed the player actually knows about orcs/elves by books, movies, etc). For anyone else in Lilith's dimension, it's only a weird modded humanoid (which is inconsecuential, since there's not many real in-game attitude reactions).
For example, there's a NPC (can't remember well... maybe a rat-kin?) and text says "he talks with Irish accent". Of course, there's no Irish people in there, but is the character who recognizes it as that.
But, now that you mention it, there could be another option.
Orcs are usually called porkers too, so a "lesser boar" could be along that path (and there could be even some funny text dialogs like "you look like an orc!"... "a what?"). It is a sort of furry, but not so furry, and would go well on the other maps.
Same way, elves could be dryads (since those are common myth creatures, and Inno does wants myth) or other fey-like kin.
It's just the player that considers them orcs, elves etc.
Maybe Inno has already planned something like that.
After all, every classic fantasy critter has a classic myth base origin. And on several cultures too.
