Instead of getting another female spider, why not get a female pastel het hypo? Since spiders don't have a super form, having multiple female spider breeders is not as rewarding as having a male spider breeder and spending the money on other female morphs that you want to work with. If you stick with your current collection, I'd also go with mojaves het for hypo, then try for hypo mojaves and hypo BELS. Or you could pair him with your mojo and your pastel, then in a few years you have the chance to try for hypo pastaves.
