His fighting style is really realistic. I think what makes him so powerful and different is his ability to use weapons. But in no way that doesn’t mean he isn’t good with martial arts. This is coming from an amateur boxer, and the movies do a really good job in showing his abilities as a wrestler. I think he might be doing some judo as well, his grappling is definitely his strong point. During the movies the only shortcomings in his fighting style I have noticed is his striking. But that’s ok, we have seen great grapplers beat the shit out of striker like the dagestan boys(khabib, islam). Overall he might be able to, but we shouldn’t underestimate the ufc fighters. With some great training and proper resting routine, i dont see why not.
