Your list just makes FRKZ even stronger than it already is. Right now FRKZ is situational, as it should be. The wrong way to rebalance Bang would be to force FRKZ on every Bang player, which is essentially what you are suggesting.
As a side-topic I don't think ArcSys is doing any serious re-balancing. At most expect some damage/frame tweaking (fix some things, they might get rid of Taokaka taunt loop, Hakumen infinite, buff Rachel, etc etc). I don't think they would tweak Bang the way you are suggesting and as much as I'd like to play the game of "what if's" it's better to just to play the "wait and see."
