Looking at the calendar, you only have from 9 am to 11 pm on that day and the EMH at HS isn't going to help you since it ends at 10.
Here's what I think I would do:
MK first. You'll want to be at the gate at 8 in order to be in the front of the line. Not sure what you mean by headliners here, but you should be able to get 3 or 4 things done in a couple hours.
HS 2nd. Plan your FP+ for here. Ride RnR single rider
AK 3rd. It's going to be late afternoon, but they're open til 8, which is in your favor. You might be able to get FP once you arrive in the park, but you shouldn't need it.
EP last. Ride TT single rider and then just be sure to be in the Soarin' line before closing and you'll get that one in too.
EP closes at 9, so you could probably go back to HS or MK to get in a few more rides if you want to.
Have fun!
