What a larger bore master REALLY MEANS is that you'll MAKE LESS PRESSURE per pound of pressure exerted on the pedal (given equal pedal ratios)... and have a harder pedal feel vs. the 7/8" master.

Some people prefer a harder pedal.

The amount of movement at the pistons in the bore at the caliper would only back fluid up into the reservoir of the M/C, because it would arrive there (back flow) prior to having anything to do with the piston/stroke etc of the M/C. It's an open chamber without engagement of the stroke of the piston.

Can't fix the KB issue via the M/C. You're going to have to fix the flex / root causation.
