There is nothing illegal about this plan. Do realize though, that this will most likely not produce results different than simply stopping your drive system. According to Physics, the surface area should make no difference on traction on an ideal surface. As you increase the surface area, you decrease the weight per unit area, thus canceling any gain in traction. The field this year is REALLY close to an ideal surface, so you would get no "velcro effect" from the wheels simply resting on the field like with carpet. Usually on carpet, this velcro effect will increase with the number of wheels and offset the friction lost to weight spread.

P.S. I tried to explain it the best I could, but it is still probably confusing. Let me know if you have questions.
