I've done it to a few guitars. Two I have used Brad Lowe 32" conversion necks and one I had a local luthier build me a new neck with a 32" scale for a Cort B4. Of course these were all bolt on. Didn't have to move the bridge in any of these cases.
Fortunately, we did the conversion from long scale to medium scale very simply: we moved the nut up to the first fret.
