I would request a lot of different wall and wedge style computer interfaces. Also wiring and pipes traveling along walls. A oven/stovetop, toilet, sink, bed, cabinets, drawers, and any other futuristic household stuff you might have on a ship. For bridges animated terminals for different stations such as navigation, weapons, communications. Blocks you would see in a med bay as well. How about all the numbers and letters individually on blocks?
Also different textures for floors/ceiling like grates/carpet/marble. Some new blocks for walls would be cool to. Well that is it for now. Goodluck
