Is This Not A Viable Strategy?

I think you're overestimating the difficulty of balancing with others on the bridges. Yes, a lot of people screwed it up in Week 1. But it's really not so hard if you do it correctly. (We looked at this for triple balancing in elims, though we never did it. The 2nd (bottom) guy has to move. If you're new, try to never move away from your alliance partner.) By Week 3 teams should be better at that. Certainly, you don't have to practice with each team--and I'd venture that you'll face some resistance to actually setting that up.
