I was bored and I had an inspiration, Dooku's Solar Sailer. Here's the result:
Details: It's tall enough for 3 regular minifigs sitting down, and one droid pilot. Width: 9.5 inches and Height: 3 inches. Droid pilot has it's own special seat.
Side Note: I have around 30 of those blue ledge-type pieces. It's only in two sets, but my local Lego Store had buckets of them. Gallery when public. (Link.)
