So let's talk about a Remake.

The point is, WHO would we get to voice for WHO? (who/whom? whom/who? I still can't get that right.)

whom/whom

To find out, answer the question with pronouns. If you'd use he/she, then it should be "who." If you'd use him/her, then it should be "whom."

e.g.
We would get Cate Blanchett to voice Celes.
i.e.
We would get her to voice her.

Who is the subject, the object is whom.

Doesn't that make it who/whom? Because the first "who" is the subject, unless I'm severely mistaken

That first "who" isn't the subject of the sentence, "we" is. Which noun in the sentence is doing the verb? Ewww, that sounds dirty. "Would get" is an action being done by "we."
You could move the sentence around to make it clearer: We would get whom to voice for whom? You can see there that "we" is clearly the subject.

Sephiroth. That sounds terrible. Not kidding, if they do that I'll never play another SE game ever again. Not that I'm against cel-shading or anime style, it just doesn't fit FFVI. At all.

That video reminded me, one of the big things for me is the sound effects. The early FFs had spot-on perfect sound design. The fizzy sound of the Aura Bolt, Edgar's tools, the sound of opening a chest, even the menu sounds were specific and seemed to fit. And I think part of it was that the sounds were dirty, earthy, deep. I think some of the later games move away from this toward flash, glitz, and shine which feels much less immersive for me.
