safe setup for a MMP?

[Semi Pro]

so here is my set up on my twinforce i built for my GF to drive when we go out bashing, i am wondering if i can get away with useing a MMP instead of an MMM.

im not going to lie, its a big heavy truck, but is set up to go slow and it will have about 60-70% punch control and medium start power

fully loaded and ready to run it 12.286 lbs and is geared for 32mph
