Sure, there are lots of ways to change HM so the button feels good to press. That AE funnel would be interesting because it adds actual gameplay, you would need to make a decision as to how to proceed, and it would give hunters a situational (yet minor) edge over other classes in AE groups with a priority target.
I'm all for changing HM to offer real gameplay and making it cool. Anything so long as it isn't a boring button you press to make your other buttons work right.
