Here's my take on how Luke Skywalker looked in the Jedi Academy: Leviathan comic series. The comic depicts him as being more muscular, kinda like the first POTF2 Luke. Based on many of the novels, I felt Luke should look more regal, so I gave him a more stern look.
To make this figure I removed the head off of an Episode 1 Obi-Wan(Jedi Duel) using the pop & boil method and did the same thing with a Dark Empire Luke. I then cut the little knob off the Luke head joint, and placed the head on top of the Obi-Wan body. The remaining joint on the head fit perfectly into the hole in the body, so the head had full range of motion, as full as it gets for a toy. I used the Obi-Wan body cause I just digged the tunic that Obi-Wan wore. To round out the figure, I added a cloth cape from the E1 Naboo Accessory Set and a spare Jedi Luke saber.
