Replying to Learning 3's with a summer setup

my season's over but i'm putting my summer setup back together. One of my biggest regrets this season was not taking the time to learn 3's, and I was considering the possibility of learning it with the help of my setup. Aside from getting the basic technique down on a tramp, has anyone ever tried it on a dryslope or backyard setup? I was thinking changing the lip of my setup for more hang time and then just putting rugs, turf, msnow, etc. in the landing. as someone trying to learn it, i'm def gonna need more space/time in the air, but maybe I could throw something together to get more if this is even viable
