lesser pieds are being done.
a visual pied with just one copy of the lesser gene (not blue-eye leucistic) tends to be an all-white snake with dark eyes. people do that because piebald white is a very pure and bright white.
WOBP has a few pictures of mojave pied, they have a lot of white but still some pattern and dark patches. its a matter of taste, but i see why you would want to aim for mojave pied.
but super mojave pied.... i dont know. you could go for dark eyes and a perfectly white body with lesser pied, or you could go for a BEL with super lesser or lesser mojave. both options are easier to produce and easier to identify.
