To be honest, if you wanted to convert the 3D deckplans to 2D you could probably release them in groups of 10 or so (PDF & JPEG) on DriveThruRPG under the TAS license for a few dollars a group. You could also do modules for FG of them as well. If you spend the time on it might as well reach as wide an audience as you can. VTT is good but mini players and tabletop is a much larger audience.
