You've listed just two speeds. Is the gearing from the 6" to 4" wheels setup to keep the two types of wheels at the same speed? If not, then you really have a four speed drive.
In my mind, one of the benefits of octocanum is that you don't need shifters. It's already providing the benefits of a two speed if you gear the Colson wheels slower than the mecanums.

the way that it is geared, the traction and mecanums are 1:1. but if you factor in the efficiency loss with the mecanums, the slightly larger radius makes that up, making the speeds of both modes about equal. The advantage shifters give, is that we have all the pushing power in low, but in high we can still go 21 ft/s in traction.
