What if Sasuke never lost the curse mark? How powerful would he be with all his doujutsu on top of the curse mark?

I like to imagine in such a scenario, Sasuke would- Unlock a 3rd level of the curse mark, equivalent to the Naruto SM What if he activates the Susanoo after entering CM form? I think the Susanoo would have wings similar to the wings in CM form. Also, the Susanoo would be infused with sage Chakra at all times. That would be super OP.

What if he fuses these modes? Like, Susanoo and CM would activate simultaneously? How cool would THAT look?

Any thoughts?
