Are threadless forks made thinner walled than threaded ones?
I imagine non-carbon threadless steerer tubes could handle a quill wedge. If you can put the wedge where the threadless stem is that would give you some peace of mind. If your upper bar is for accessories, you wouldn't really need to reef on the quill bolt much.
