I've had the same exact thoughts. I believe it's possible but hasn't been done. Or at least not made public. It's a gamble of long odds against you. It would take years of trials and disappointment. But OMG what a payoff if you could do it and prove it. I think you would first have to acquire 2 Mojave het pied to attempt a super Mojave het pied. And then do the same with mystic het pieds. if the odds favored you, you could have a whole clutch of mystic potion het pieds. Then breed them back together and hope really hard. Sounds accurate to me.
