The spellcasting check modifier seemed to me like an easy way to integrate two ideas. Also a way to eliminate some of the "skill tax" normally represented by Concentration (especially given all the autohypnosis abilities we're giving it, making it less suited for casters).

Also, the by-the-book Concentration DCs (which are mostly what you used) are pathetically low.
