Some awesome ideas. Many of these smaller things don't come up in discussion often, some of them don't even need any extra animations, and are just space savers, or elements of realism. Urinals, doorbells, landlines, separate cooktops/wall ovens, and most importantly, regular versions of the telescope, microscope, and anything else that's cartoonishly large.
Just thought of something else... Buyable version of the CL apartment problems, specifically the electrical panel.
The "quirks" are tied to their respective objects, not the lot trait, so adding movable/deleatable clones to the available Debug object catalogue shouldn't be to difficult.
