BIG QUESTION????

I doubt you will have any problem if the sharp edges are gone. It's usually an issue of detonation damage (cracking, melting, etc.) and not directly related to crown thickness anyway.
In other words the piston strength should be fine as long as you don't detonate.
With detonation even very high dollor pistons will die.
