Though I've never had direct experience with this, I'm sure it would have many of the main problems associated with mecanum wheels, though probably a bit worse. The main concern is that you'll get pushed around, since omniwheels have so little traction.

If there was no chance of defense, it might be a good idea. However, I get the idea that there will be a lot of pushing this year.

Disclosure: I have never personally worked with this type of system, but I have seen it used both in person and in video.

When the omniwheels are centered on the frame like this, the robot tends to get tippy in the corners when turning. A way to overcome this is to make the frame low to the ground or 'wheelie bars' in the corners.
