It isn't possible =/ Tried this F3 Chaos scrolls don't work either, but those say "Cannot be used on CS items."
I tested it on my old panda's hat. I haven't tested this on wedding rings though.
EDIT: Actually I think 1% Slate scrolls have the "Not available on Cash Items." message on them. Not sure about the other % ones, but I don't know why they'd be different.
