Actually sorry bro, but no..
You'd have to have a het pied and a pastel het pied to hopefully hit your chance of a pastel pied. Your pastel pied is a 1/32 chance, and just a normal pied would be your 1/16 chance. if you did het pied to normal pastel you'd have a pastel 50% het pied. if you know your het pieds a 100% het pied for sure.
may i suggest a little bit of reading material...pick up KEVIN from nerds book "The Complete Ball Python". That explains everything genetically. or you can go to www.worldofballpythons.com and they have a genetics calculator that'll show you exactly what you'll get from this pairing to this pairing that you enter.
