Put both on progressors, or, leave on the small kit, and test to figure out what the combo wants with start time/percentage, and pill size for the second system. There is still a lot you can do with the 7al3, just have to be a little more creative. Are you running 1/4 or 1/8, and what kind of trap rpm would your engine combo be happiest with? I would have the rear gear to go the quickest and fastest, then make chassis/and engine tune changes as needed. The 28x10.5 tire is very good, and I have seen high 4.80's in the 1/8 from this tire.
