Will I get penalized by the referree by using the soccer ball as a weapon, in a game?

LMAOL you sound like you just want to hurt your opponent. It all depends on how the referee see the play. It's likely that if the other guy ends up on the floor, he could call it a foul. But heck, some guys have been intentionally hurt on the penalty zone and the stupid referee wouldn't even call the foul. Try and find out =^)
