Just doing a bit of math on your new wheel cylinder diameters. The areas in square inches are:

15/16 = .6903
1 = 0.7854
1-1/16 = .8868
1-1/8 = .9940

Assuming I did my math correctly, these differences are about 12-14%. Though I doubt you'll have any problems with these larger cylinders, you may experience some differences from the stock diameters. Since the cylinder volumes are larger, it will take a longer stroke of the master cylinder to move the shoes the same distance, and it will take more pedal pressure to achieve the same force on the shoes.

I'd be interested in hearing of your evaluation after you get some road miles.
