Ordinarily I'd say possibly, but I don't think I want something that ascribes moral or ethical behavior so heavily. I've also limited alignment to deities, outer planes, direct servants of deities, major powers, and then things like organizations, guilds, kingdoms, churches, etc.
A knight might be a member of an order, but the knight themselves, their superior, and even the order's captain would not be aligned. The idea being that free will precludes alignment, so only very specific things are aligned. Being in the presence of an aligned being, then, is pretty terrifying because... they have cosmic moral and ethical goals and limitations and obligations and duties. Mortals need to band together to create something with enough willpower to truly be
aligned.
So, there will be deities and major Fey powers that have alignment, but otherwise humans, orcs, elves, drow, goblins, and even other fey, will have open-ended cultures, ethics, and morality determined by their choices and associations. People tend to think of mythological fey as Chaotic, but look at them closely. They have strict hierarchies and placement in it, they are concerned with rules and contracts and natural laws, etc. The fey are just as Lawful as they are Chaotic. Sure, some myths say those rules were imposed on them, but that's not universal.
I like Praxis because Goblins as a whole seem to be do-ers. Goblins are commonly artificers, hobgoblins practice warcraft, and bugbears... well, not every goblin has to follow the same path (Edit: I think I'll make them hunters). I haven't quite decided what they will be doing. Some of the subraces of Drow and Elves like crafting and creation, too. Imagining Praxis as a warren of caves in a steampunk techbase, or something like the world of The Labyrinth would be interesting. Praxis is ideas given form.
