That can work sometimes, but at this point you're probably over thinking it. Realistically, trying over and over to feed a snake that's likely stressed from a change in environment is just asking for trouble. It hasn't been that long ago that he fed last. Step back and leave him alone for a few days. Give him a week of not interacting with you, then try again.
When you do try again, offer food at night, when he's likely to be alert. You might even want to offer live prey until he's eating predictably. THEN worry about using clever tricks to entice him.
