I think I can decipher it...

Anyway, I'm guessing that you're asking if the other characters not in your party level up when you don't use them. Yes, they do. So yes, your plan would work.

The answer to your question is yes, but that's also kind of boring, when you think about it. Just pushing "A" over and over again isn't too much fun, after a few hours.
