an idea that seems to work in theory...

Build your ceiling inside first, build your outside wall studs, set ceiling crossmembers on those walls, thereby everything stays tied together and ridgid.

then you block up the roof up with timbers set across those crossmembers to support your roof and remove all the rivits and such to free the roof.

chalk a line on the walls and trip the wall down.

then with a post jack just lift your roof and remove the support timbers one board at a time to lower it down to your desired height.

redrill ad re-rivet the roof to the wall

Like a big house moving job only smaller scale.
