At least as the menu actions are implemented currently, there would be a problem with that, since the information would have to be duplicated and maintained in parallel, which would be horrible. With a future reimplementation of menu actions (which I am currently trying to formulate), it would be
possible, but it would still have a couple of other problems; the foremost one being that the items that can be inputs would need yet another image to fit properly in a line of text, and I don't really think Jorb would be very amused by the idea of having to do that.
Further, up until only very recently, I haven't had a good way to render text so as to allow for such rich tooltips. However, let me provide a screenshot of the current test-client for the new combat system, as it has looked since yesterday:
