That rule really works well the way you explained it. The only modification I see is ejection.

I expect, that in the BIGS, if a runner who had just plowed into F5 to make him drop the ball, jumps up and runs home to try to score he would be met by a really pissed off catcher who has lost all interest in the ball and is ready to fight.
