I agree that it's not an issue. Game permitting I'd be surprised if we didn't run a setup very similar to 118's 2014 bot this upcoming season. The idea I presented would give an ideal set of linear speeds, but would likely lead to a few other issues down the line. For example, your center-to-center distances would no longer be nice easy numbers.
The width of the vexpro sprockets can easily be solved by shaving them down a little. Beware of the 16t sprockets, however, as we found that the chain would grind on the bearings, as Mason pointed out earlier.
All in all, 118 has it figured out. Their system is the easiest Texas Tube I've seen so far, no need to reinvent the wheel.
