I would go:
Axanthic Black Pastel x Pinstripe het Axanthic
Albino het Axanthic x Axanthic het Albino
Axanthic Black Pastel x het Axanthic

I appreciate the double recessive, but I honestly don't find snows that exciting. I do wish someone would find a combo to make them exciting however, they are severally under priced imo. In your shoes, you still have the parts to make them, so I figured I would do the same. However I think a super black pastel axanthic might be a really interesting snake, so I would personally work toward that.
