can you lighten a converted Revo without compromise?

i have performed the mandatory trawle and search but found little if any related threads to my conundrum. i have a converted revo 3.3 with all of the mmm and neu goodies and have come to a point where i have noted the tremendous weight of the mighty beast. i trust that traxxas have built the revo ruggedly for what hell we throw at it, but can there be a way to lighten without taking away its ruggedness? sure the driveline is tubular and chunky and the solid suspension pushrods are nice and thick and the enormous bulky diffs so nice and strong to endure the BL punishment.

however it doesnt help with the whopping 5s lipo pack slapped onto its back.

what mods will allow its strength to be retained but rolling mass to be reduced?

FTR it weighs around 5 kilograms with battery.

any pointers welcomed.
