Just because they are from 2 different localities shouldn't make a difference. The only difference between the 2 localities that I know of is color and pattern variations. These are 2 things you will get even breeding snakes from the same locality, they will all be a little different. I am not an expert on breeding snakes by no means but even a gabino,
gaboon x rhino, they cross locality boundaries all the time and are 2 totally different species but they breed and have successful clutches. My answer is breed them.
