If I ever get the chance to play D&D I want to play a monk, but I would want him to be like the famous Mexican pro-wrestler El Santo. This works well because there are in fact lots of old movies starring El Santo from the 50s, 60s, and 70s where he pro wrestles against werewolves, demons, the swamp thing, mummies, and so on. Having him be a D&D character who fights monsters just seems logical.
I definitely think it would be necessary to write a prestige class or something for lucador. Maybe lots of really powerful grapples and power attacks that can be used when jumping from an elevated position. Or a special clothesline maneuver that upgrade the Attack of Opportunity when someone moves past the luchador. It would be the best campaign ever where a luchador defeats the evil vampire lord at the end of the campaign after a desperate prolonged battle with a German supplex.
