Eh, as long as we don’t start with the Eternal Mongeko I think it would be fine. Since the regular Mongeko doesn’t have the perfect Susanoo which can destory mountains and the regular also has the blindness side effects which would deter regular usage of Mongeko.

As for the other problem, I think it can work as long as they have some sort of difference in fighting style Like one could be focused more on the copy aspect of the Sharingan and be more ninjutsu based, while the other could focus on the Illusionary aspects and be more genjutsu based or have different secondary Chakra natures or have one of them be more close ranged while the other more far ranged or give them each a signature jutsu.
