Went on a YouTube wrestling binge and found these. . .apparently Championship Wrestling from Florida had something of a supercard going for a few years which featured a crossover with multiple promotions, and in between some really dodgy bouts, there's some early work from Muta and a couple others to be seen.
Dunno if you've seen these or not, but I thought they might be worth a look.
I have seen Battle of the Belts 2 and 3 and I wish WWE would put them on the Network. In fact I reviewed 3 a great many years back and I'll repost it right after this e-mail!
