Can I crypt the ASProtect section ?

Yup, two protectors will not only help your protection but, probably, may cause compatibility and/or stability issues.
You would have to get acquainted with technical aspects of wrapper based protections to understand they are to be used only once. OEP, IAT, layers, stolen code, bla bla - all the stuff is applied to the last layer (first protection) and you want to add another layers, but they will give no additional security since the final layer will stay the same.
