I took my original attempt at this and completely reworked it now with the appropriate parts. The only thing that remains from my first attempt is the Darth Maul torso. I replaced the lower torso and arms and legs with that of the Wave 5 Jedi Luke. Even the neck post pops out when you dis-assemble Darth Maul's upper torso leaving a spot for me to place Luke Skywalker's neck and collar into place. The arm/shoulder joints were completely bored out on Maul's upper torso and I trimmed Luke's shoulders down to plugs that just popped into place. Pretty simple over all. I added a soft goods under-tunic on the lower torso in keeping with Hasbro's look.

*** Update: I added a cloak using a brown fabric from a $5 Monk costume from the clearance rack. The hood is wired (*wink FitzJedi) for total control up or down. A fitting addition to this custom.

He's ready to sneak into the palace!
