Just a suggestion...

A friend of mine came across a similar situation with an old Kay jumbo that belonged to his grandfather. He was going to relegate it to wall-hanger status so I asked to borrow it for a while. It turned out to be a great slide guitar...we had a riot with this guitar experimenting with open tunings and learning different riffs.

Maybe you could install a taller nut so the strings are elevated equally across the entire fretboard and do the same...
