Roger,
Not too worry.  It you made the effort to pad and support the hull for some distance, let's say eighteen feet along the side she is resting on, then you might get away with your leaning on her side idea.  The difficult item would be to calculate the compression of the cushioning/support material to eliminate any point loading.  I might also remove the mast first.
 
The time/money spent on the padding and calculations might be partially offset by the increased ease of doing the bottom job.
 
You are up for it, go ahead and do the calculations...........................hey how about having a truck dump some loads of sand next to the boat.  Then make a template to sculpt the sand to match the hull shape and slowly lay her over into the sand pile?  First cover the sand with Tyvek sheeting or polyester sheeting to prevent minor scratches from the sand pile.
 
If the crane is available for some time then make a net out of nylon straps, remove the mast and have the crane operator lay her over into the net and lower to just above the ground.
 
Hummmmmmmmmmm.  Maybe you could get some of that invisible paint that Poppy the Sailorman used against Bruno.  That way once you painted the bottom you would never have to do it again.

Thanks everyone for the feedback. Looks like another high potential idea
bites the dust. I am gelling my thoughts on a false transom that folds down
to become a swim platform/dingy dock. You guys are gonna love it! George,
I will look into the swimming pool idea further and untie the dingy; I was
wondering where that thing had got off to.
