Splendida x calligaster?

[travesty]

Has anyone ever encountered a Speckled Kingsnake x Prairie Kingsnake intergrade while herping?

Is that even possible since calligaster is not part of getula? We have both in Oklahoma. Their range overlaps heavily but I can't even find examples of a mix on the interwebs.

I wouldn't want to try it, I'm just curious as to what they would look like. A lot of intergrades/hybrids look ugly to me, but they are definitely interesting.
