He doesn't seem to want to work in the recessives, which I can't blame him for.

I'd say get a lemon pastel or a fire. Also drop the female lesser and have your lesser breed with the other 2 females. Mojave x Lesser BELs look identical to Lesser x Lesser BELs. Unless you intend to sell for the most you can, in which case drop the Mojave. Lesser combos will make you more money than mojave combos.
