Oh there's no end to what they could do if they got a license. They could easily do multiples of wrestlers due to ever changing attires. Use the boring business suit figures for announcers and authority figures. And while I know it would never happen, a ring with guard rails and an entrance ramp would be amazing to have in minimate form.
I understand not being a fan of all the "classic" wrestlers, and to each they're own. I'm a big fan of the current group of preformers in the wrestling world. The classic wrestlers, like Luke is making, just hold a special place for me. As a kid it's what I watched with my dad and have a lot of very fond memories of.
That being said, whether it's classic, current or a mixture, I would be all over a wrestling minimates line.
