This sounds like a very useful topic, I'm pretty much do the same like yours, also, you may know this already, you can use the Piano bank on chord 1, and guitars bank on 2 and 3 as well.
Important note, i found out the hard way that if u do all changes in global not single, during fills and break these changes still running, sometimes sounds kind of funny
