I have looked at this stuff a lot, and my biggest concern with "the box rule" is that you have to make the box big enough to fit the existing cantilevered tires, on the biggest wheel currently allowed in the class. That would mean this:
EP - 25.5" x 25.5" x 11.5"
FP - 23" x 23" x 10.5"
HP - 23" x 23" x 9.5"
Sounds simple enough, but then you have to think of the repercussions. With widths that big, you have to be ok with 10.5" wide Hoosier radial's on a 15x10" wide wheels, that will absolutely destroy everything else, and cost about $350 a piece. And that's just in FP. You then also have to be ok with that same tire being used on your competitors 2000lbs WhatsIt as your 2600lbs ThingamaJig.
If neither of those things bother you, then maybe The Box Rule works for you.
Have you considered an "existing rim restriction or box rule". Allow any tire on the existing rims sizes, since we know how far those can be pushed, then also designate a new box size to allow larger rims with "reasonable" sized tires. This could be sized to allow 8.5 inches of tread on 9" rims, but not 10" rims, etc.
