i know for novas if piston fitted wrong way; it'll hit the crank but for piccos, even if fitted wrong way, it'll not hit the crank at all...

Once the piston has been worn into the sleeve. This creates a very precise fit. If you place the piston in 180 out this precise fit is lost. Remember due to the earth gravitational pull nothing can never be perfectly round. In a nut shell don't do it unless you want to ruin a engine.
