I honestly don't think any of them need to appear for a crossover with MMPR to work. They just need some stunt people in the suits and some VA's doing reasonable impersonations for the voices.

That said, if they could actually get someone in for a cameo, the one I'd like to see the most is Johnny. I would say David, but I can't imagine them ever getting him in for a cameo. I'm still kinda surprised that Shout Factory got him for some bonus feature stuff.

Even though several fans are tired of him, I would be ok with JDF making an appearance. Though I have to admit, it would be nice if he wasn't the only one.
