I think by the time you've worked out a reliable way to prop up the 
back of the keyboard to bring the thing to the right height under the 
set-off rail you might do better ramping the action in and out and 
doing it a few at a time, but you can take measurements and try. You 
need to sheck the blackleading and burnishing of the jacks both at 
the front and underneath and devise a way to hold the jack firm as 
you work on it so as not to strain or tear the vellum.

The Bösendofer I had was only just over 5 feet but very loud indeed 
with a tremendous bass.  The front of the soundboard was floated on 
an arched maplewood rail.  I don't know if other makes were like that.
