The one issue that may arise is you would not have any easy way to tell which BEL is a lesser super, which one is a mojave super and which one is a mojave/lesser.
Although subtle differences usually exist, like super mojave tend to have the purplish heads, having a clutch of all white snakes might also end up a bit confusing to know for when you want to use one of the BELs as a breeder and you aren't sure if the mix will give you lesser mixes or mojave mixes or either.
But a whole clutch of solid white BELs.... nice.
