Yes, please. I've spent hours cladding rooms with partitions because I hate the windows and raggy red ends on the shirogane house, and the pillars with their oversized hit boxes leave ugly gaps between the furniture and walls. I love the texture of the white partitions, and while I know you can wallpaper that onto the real walls, that's not dyable and you still get the pillar/window/red rags issues. My first apartment where I actually wanted the hingan walls with crystal wallpaper, I clad it in blank hingan and wallpapered each to cover the dead zones from pillars and the ugly windows...and swiftly went mad from accidentally clicking near one or the other of them because they're always targetable. My mistake not knowing that at the time, but it's silly that the options were frustration at the visual flaws or frustration at the functional flaws.

Ideally, I'd like full customisation (windows on/off, pillars on/off, walls replaced with any partition model complete with wallpaper or dye options as relevant). But at the very least, swap between the three locale interiors at will so it's either something you can work with (smaller hitboxes, nicer trims) or like outright.

It could even be a vendor or crafted thing, like the exteriors, roofs, fencings, etc. or existing partitions, so you need to buy/craft an interior to re-clad your house/floor/room, meaning the gil-sink isn't avoided by not having to buy twenty partitions, and crafters don't lose business from the drop in demand for multiple wallpapers to cover individual partitions as they have something new to make and sell.
