According to some exotic RFC, a proxy should handle a URN URI and translate it into a SIP URI (or route the request to a predefined proxy which handles it). But no specification defines how a HTTP URI should be translated into a SIP URI (or other kind of URI).
Because it isn't specified, it can't be done? One could probably think of some scenarios where a MESSAGE request with a text body and a mailto URI does make sense. Of course you need some pre-configured logic to make the proxy understand what to do with it. If it knows where to send the request to, it can happily do that. No need to have a SIP URI for that purpose.
