I'm also one of the nominators, and I nominated both Apocrypha and Grand Order. I really strongly want those to be separate so that their iterations of characters -- especially in Grand Order, which borrows so many characters from elsewhere in the franchise -- can be requested/offered without confusion.

I don't think it would help match people to combine them into one fandom; it would just limit who could request/offer the fandom, because you'd have to be familiar with all timelines instead of just the one you were interested in.
