So what we really need is a plate heater, something that will let=
 the plate and strings warm evenly...hmm....?

As Laurence wrote, it will slowly settle back.  What happens with=
 temperature changes is that at first the strings warm up and go=
 flat, then gradually the plate warms up which makes the pitch go=
 sharp a little.  If you close up the piano during the opening=
 parts of the concert, it will drift a little, but the plate=
 changes slowly.  The strings will then warm up quickly once the=
 piano is in place under the lights for the performance.
