I'm no expert at this, but would it really take up so much memory? The wing types are preset, the furniture layout within them is preset, all it would take is the option to "move" the wings at the planning/construction stage.
No, it wouldn't, but there is obviously something going on which prevents the presets from being interchangeable, though I have no idea what that is. What's even more baffling is the options aren't locked in the
type of option, meaning I can put an alchemy tower or storage room on the north side and both of these are very different plans. I would be more understanding if we could only put a tower on one side, but the fact we can build a tower on all three sides has me scratching my head why we can't interchange.
I, too, would have loved to be able to customize my house a bit better. To sacrifice a kitchen for a trophy room was a difficult choice, so I elected to build two houses for two different purposes: one for residential living and the other as a museum. If you'd like to visit, it's right behind Whiterun and entry is only a mere 2g!
