The side load from pushing seems acceptable, front and rear a bit less. With some good programming and driving, this should be a good system. It might even roll straight up the tower.
I'd be worried about defense -- which I think will be huge this year -- and mecanum wheels, while not as bad as many would like to think, do suffer against most conventional drives when it comes to pushing matches.

Pyramid protection helps, but doesn't eliminate, the disadvantage -- and I think it can be argued that near your alliance pyramid the mecanum drive might very well have the advantage.

Overall, as a person who personally really loves mecanum as an easy-to-implement and comparatively cheap omnidirectional drive system, I'd say that pure mecanum is at a disadvantage this year (for exactly the same reason that disk pickup is really nice but not required)... But it's not crap.
