No, that is how Luke should be, facing up. If the falcon was sitting on a table, luke would be facing up. An interior here is possible, but for other UCS is nearly impossible, cept the UCS Y-Wing.
One reason I want to buy this set, and this applies to all other sets, is that I love building, and the looks, but the build is what I enjoy most. I had the time of my life building my ISD, I just have to figure a way to get this.
