Um, no. Not only will this retroactively make all intermediary caches non-conformant, it'll also make them completely useless, because of the large (and unnecessary) amount of variance in User-Agent headers. I understand there are security issues here caused by CORS, but that doesn't give you the ability to force changes on the rest of the Web.
