On note about frameships and mega-frameships - the key is to fracture it up. You basically have two traits that work together to allow for mega-frameship operation. 1: Frames only make attached blocks, but not secondhand attached blocks. 2: A frame with a cover on it, touching another frame, will not pull the second frame, though this WILL cause issues with how the motors push it.
I've been doing a bit of research in how to make extra-sized frameships and how to get them to behave correctly. With creative application of panels, covers, non-frame blocks, and especially sticky pistons, you can achieve some very fun results.
