The problem with this, just off hand, is that to block breaker, you have to, you know, block. so it's not really a way to mitigate 50/50s because if you already have blocked the 50/50 you already in a position to punish as the reward for blocking it. Why would you block breaker to reset to neutral in that situation?
I'm honestly trying to see how this would help, but if you can block enough to use the block breaker you should just punish after the block anyway. If you're trying to stop the 50/50 situation before it gets to the point you have to guess with block breaker, it's not going to happen because the hardest 50/50s to block are the ones that happen on first hit.
