I am going to get a little bit of a raise on the height of mine by going from 6 inch wheels to 8 inch lawn mower wheels (1 inch raise). Also plan on putting a caster on the 3rd leg to level it out since the third leg wouldn't be long enough. I am not very tall though and just wanted it to sit closer and look similar to my performer.
You could look into a master touch leg kit, a new triangle at the bottom (they are a different size), and some aftermarket wheels. However, that is still probably a $70+ expense that I wouldn't do unless you got your grill on a close out or cheap.
