LoL, Steve!
Okay, in all seriousness, I think your trouble is that you have a perfectly unique plant, but if you breed it back to something else, you run the risk of getting what already exists.
My thought would be to see if TET Pink Stripes is stable enough to get your hands on. I'm pretty sure it was Bill Waldorf who was working on it. I know there was offspring produced from a TET Pink Stripes, so maybe? That might help you keep stripes in Clown Pants' lines. From there, you may want to bring in some thick-petaled genetics to give it excellent substance...and dark-colored or bright-colored, daylily genetics to maintain the rich coloring that you have. (Please don't go pastel!
) I see that clown pants has teeth, too, which I didn't realize before... Maybe try to increase the number of white teeth without letting them turn yellow?
