Changing the ball?

[Danvrapp]

So had a game Tuesday where, halfway through the 2nd quarter, coach A1 comments about too much air in the ball, could we take some out? My partners and I discuss this during next TO, and after the 2nd quarter ends an end we notify both coaches we'll do it during halftime. For the record, the ball was probably bouncing either slightly high, yet in the acceptable range or--depending upon your view--slightly too high to be acceptable.

No one complained about the ball the entire 2nd half.

Here's the question: Is there anything against doing this mid-game? Was this a situation where we just tell the coach "This is what we started with, this is what we'll finish with." Since the R "verified" the game ball before the game began, is there any rule against swapping it out after the game begins?

For that matter, is there ever a time (for reasons that I can not currently think of) that you WOULD/COULD switch or alter the ball after the game began?
