You've outlined the possibilities pretty well. I don't think you want a custom analyzer though, consider a custom UpdateHandler and overriding the addDoc command. You can freely manipulate the document at this point, adding or removing fields etc. So see if the incoming doc has your original field or not and add your new boolean field at that point...
Or, even simpler, if you're indexing from SolrJ do this on the client side.
