I recall that someone added a slightly larger foot to the bottom of the stand. You have to watch that it won't interfere with the left side can.
I also remember that someone used to put a baby or toddler running shoe on the exiting stand. They said that by doing this they did not have issues with it sinking in hot asphalt or soft dirt. They would get a pair for a few dollars and then have a couple years out of them before needing to replace them.
I added a small foot with toes to mine and ended up with clearance issues with the can; by the time I got it ground down to a size that it would clear the muffler all I had left was what looks like a flip-flop for an infant......
I think that the baby running shoe would be a hoot! Go down to the local thrift store and buy a used pair....
