I have a Summit

If i wanted to be able to do a quick conversion to make it more like an E-revo for
indoor track racing.. what would i need to do. assuming my summit is stock
(want to keep it waterproof)

I would need

different wheel and tires
different body
pinion change?
soften the springs?

I want to be able to swap it from Summit to Erevo and back again quick and easy
