I figure if the menus is gonna be a lot to do,
Maybe a Menu Cursor could be a good alternative?
And the RT can be the confirm (Left Click) button!
Dunno, I played a lot of Marvel Rivals and notice that seems to be good enough when dealing with Mouse focus menus.
It is preferred to have selecting menus be simple like you’re doing now.
Maybe that can be controlled with D-Pad.
While the Left Stick can be Cursor if need be.
