Kurt Angle could lay a real life smackdown on a real life fighter ... 'cause the wrestling legend says he's considering doing a real MMA fight -- and named Kimbo Slice as a possible opponent.
Angle -- who's been doing commentary for Bellator -- recently appeared on "The Roman Show" and was asked if he'd ever step out from behind the media desk ... and into the ring.
Angle says there's a VERY SMALL chance he agrees to a fight -- since he's 47-years-old now -- but if it does happen, he's already thought about who he wants to fight.
