Don't see why not tbh, originally I didn't do it because of the issue with walls, but if we're fixing that it should look nice on rooves and wouldn't mess up anything too much.
Speaking of which, @Thamus_Knoward do you think your wall fix is ready to be implemented once I get back?
You're still on the road :O Man I thought you'd be back already! I've done the vanilla walls, iron rungs and regular ladders so far. I wanted to give furnaces and household items a go, but I haven't had the time yet because in addition to making the models I also have to remake the textures slightly. If you want to wait for a big release that could be it, if not, I'm happy to only show you how to implement the wall model change in WesterosBlocks.
