I once had that same kind of idea but I canceled it. Because semblance have to be synch with the character's fighting style or their weapon utilization.

I question myself what if my OC mimic a particular semblance. Then I think that the semblance would be incompatible with my OC's fighting style which is the part when thing isn't RWBY spirit.
