a well trained and conditioned TCMA guy should be able to compete in any striking only venue with any size glove...they of course have to train for the ruleset and equipment that may be called for. Training/sparring in school w/ sanda/sanshou rules is a start. Being open for anyone to walk in to your school for sparring (with waivers and a good attitude from them) will help them get experience against unknown opponents. So will going out to other schools to spar with them.
They should also do well in a venue with throwing as well.
But, they'll have to cross train in a grappling art to learn how to move on the ground against a grappler unless you have the skill base to teach them yourself.

"Is enlightenment even possible? Or, did I drive by it like a missed exit?"
It's simpler than you think.
I could be completely wrong"
