Im by far no master breeder 0r anything close to being a breeder but am just as curious as you and having fun crossing and stashing seed
the more stable traits they have in common the more stable they will be ie ( blueberry x ak47) x ( blueberry x master kush) you dont have to be a breeder to get stable seeds this way
the more different they are ie lanky sativa x short stout indaca the more variation you will get. so choose the ones you want
if ya have the time and space i would say just do it and see what you get. save some pollen from your super auto favorite male and hit your favorite super auto females for a couple generations and let us know how it goes
Good luck and peace out my auto flower friend
