Well, no.  If X doesn't know about it, then you mean that we now have
two security problems: the allegedly secure X, and the anything else
(which isn't secure at all yet, by hypothesis).

No.  The best you can do is the trusted/untrusted distinction.  This
is supposed to give you some protection from keystroke logging and the
like, but without an encrypted channel all the X traffic is still open
to anyone.
