I am hoping regional, spelltouched, mutation, and possibly reserve feats could be added. Among these, ones i hope to add to my character are Arcane-Blooded (mutation), Dreadful Wrath (regional), and Storm Bolt (reserve). I understand that the mutation and reserve feats may be difficult, but they are doable. I found a nearly-complete list of feats here:

If anyone else has suggestions, pop'em up. if fairly sure the makers would like to know what their fans are looking for
