Even if you used 5/8 on the wheels it wouldn't work on the center, since you step 5/8 to 1/2 to 7/16 on the gearbox output shaft hexes.
A big part of why we don't switch is backwards compatibility. Everything we've done since 2007 is interchangeable with any subsequent robot. This was a big help in 2010 when we were able to make an 8wd drive base (identical to our normal one except riveted instead of welded) in approximately 24 hours in the first two days of kickoff in order to test bump climbing ability.
