Robbie Kay. He acted as Henry when they switched bodies so he already knows the role and is familiar with the character's mannerisms/motivations/etc.

In Sliders, when one of the main stars of the show left - Jerry O'Connell, his character was literally merged into another character. So if Jared ever decides to move on from Once, the same thing can be done. Peter Pan's body can be reconstituted (maybe because it once shared Henry's soul?)  Then, Henry's essence could be somehow "saved" or transferred into Peter Pan's lifeless body.
