Given the amount of time that would be put into building these (taking apart the wheels, rollers, testing,ect.), I think a team interested in Omni's could easily design something else that fits the bill better (Such as Butterfly) and be much happier with the results.
I think with the right wheel configuration there's a way to solve some of the pushing problems. I need to think on this one a bit.

The benefits of this is that it would be a direct swap out for a normal omni drive, so you would only need basic testing in the offseason. With butterfly and similar drives, there is a LOT more weight involved and it has to be custom built for each robot. Plus, you don't get a lot of push power in mecanum mode. So IF (big if) a modded omni could be omproved it could offer an advantage over butterfly drives.
