The only fly in the ointment here is that the recommended rim sizes are 15x4.5 to 15x5.5, so I will be flattening the tire slightly. Anyone do this before? Any insights?

Bart,
You are within 1/2" of their "recommended" rim width, which is not going to be a problem. The tire may be slightly harder to seat on the rim initially, but I doubt you'll notice much, if any difference between a 5.5" and 6" rim. I strongly agree, I would not consider cutting up the fenders until you exhaust all other options.
