That don't matter to me. I would just like to have them in the game. Plus, even if it did, I would have to give it some serious thought to think of abilities. For one of their passives at least seeing as some of the akatsuki do it for each other. For other guardian shinobi twelve on the team, raise their stats. That or for other guardian shinobi twelve or konoha ninja on the team raise stats.

If at all possible though, make asuma mid to high tier. I know if he would be high tier, he'd be long time before I get him, but still, be nice for that. Asuma, wb asuma are support. If this one were to get added. I'd love it he'd get to see a p1 spot, if not p2 instead of being a support. Even if he isnt gonna be mid to high tier and made as support again. I would still try to get him.

Edit: In assist links, If Asuma or chiriku being use have have other guardian shinobi twelve are selected, then have an attack together if that can be a thing.

Edit 2: Just thought of this. Even if he isn't made to be mid to high tier, and made to be support like the other ones. Seeing the asumas all have something to do with chakra. Make this one of his passives. While alive on the field, all konoha/guardian shinobi twelve mysteries scale up depending on how much chakra you have. Though I can see that as a passive, even though he'd be a p1 ninja, like shark kisame does.
