Yea, a few 1Dx's and I would be tickled... Then again, I don't think I could acquire enough CF cards to shoot a full game (something about hearing it burst out 10-12 fps shots at a time may get addicting). Yes, setting down a monopod with 2 lenses can be dangerous, I need to design a stand for holding monopod + whale(s). Positioning will be fun, as there are benches behind the endline. Having shot a few years back at Real Salt Lake who doesn't have said benches, the knee pads and chair would have been really nice. The lens changing thing is more a personal preference than anything else.
If I were to swap anything out/up, I'm thinking it would be going from the 300v1 to the 300v2. Or bump the t4i up to a second 7d.
Thanks for all the replies!
