I definitely suck with Gospel chops but they actually break down different rudiments with their feet aside from the hands. For instance, a lick that goes RLRRLRLL will have something like R on the snare, L on the hi-tom, RR on the bass as heel-toe, L on the snare, R on the floor tom, LL on hi-hat as double hit, repeat with variations. There are more rudiments to experiment which I won't post here because they're so complicated that I can't actually apply them.
