It'd collide with the LR Black & Zamasu unless they made it base Black & Zamasu and Black. That being said, I'd definitely love to see a base Black & Zamasu TUR which goes into Rose Black & Zamasu starting from 3rd turn and then has an active skill which allows him to fuse into Merged Zamasu.

Or they could make an exchange unit like the f2p Vegeta/Trunks and Goku/Gohan. They could balance it by making Rose a hard hitter and Zamasu a tank capable of healing. Of course they'd need to limit the exchange for such a unit so you wouldn't be able to just exchange every turn (for example you could exchange from the very first turn but you'd be stuck with one character for two turns before being able to exchange again) but it'd make a great addition to Black and Zamasu units by having a different name than the rest.
