I always liked ringers and paradox snakes. I have no problem paying a little extra for something I like even if it's not genetic. I'll have the animal for many years, look at them, feed them and clean up after them so it's well worth it in my eyes to pay extra for a snake I'll enjoy looking at even if it's not genetic. Take a look at my avatar for example, it's a champagne "ringer" produced by Brock Wagner from a champagne x normal breeding. It's one of my favorite snakes.
I don't think it's a bad idea at all, maybe you'll get lucky. I don't believe that these traits are genetic but they may be more then random. For example, I have a lesser male with small paradox areas that are barely noticable and I've gotten a few paradox lessers from his clutches. I also have a het pied female that produces ringers in her clutches. I think it may be more than random, just not recessive or dom/co-dom. Either way, it's fun to see what hatches...
