The girl's line up looks good. However, I wouldn't go for a single gene male unless its more of the rarer morphs. Like snake lab suggested calico. That would be a good choice. But if you're set on pastels, get a pastel combo. Single gene base morph males become obsolete fast.
I suggest a pewter or something similar.
In the mean time, I wouldn't worry about males yet. If you plan in getting hatchling girls, then it would take at least 2 years to grow them up. It only takes a hatchling male a few months to reach sexual maturity. So you can get males next year.
