Steve you are making me work in a way that is alien to my normal trial and effort approach, still I'll have a go.

Problem. We cannot move the fulcrum point. Solution. Leave it where it is.

Lever the stone up as far as possible, then insert packing logs between the stone (stone side) and the fulcrum. This will bring the contact point of the levers (now acting against the packing) back towards the fulcrum. Continue and repeat as necessary.

The distance to be covered cannot be much more than 3 or 4 feet.

Sorry, Gordon, if you'd like time to build a model that's OK. However, calculation shows that the distance moved by the top of a 32 foot stone from 70 to 90 deg is just under 11 feet. That's one hell of a lot of packing. Nice try though!
