They already did most of this in TOS and the rest in TNG. Obviously, most of it was not done to Picard but some of it was (looking at you, Locutus) but it's all been done better before.
I agree with whoever it was, maybe majestic, that said the problem isn't that characters are diverse but rather that there's not much else to them than what makes them different. It's that same shallowness that kind of permeates all of nuDrek.
