If you want to save both bits you'll have to re-lace it, even the drive side. Z-bend spokes are the answer; if necessary get a smaller rim, say 24", and a bunch of old spokes from a larger wheel. Figure out what length spoke fits the hub and small rim, and cut the heads off and make your Z-bend at more-or-less the right distance. It does not have to be more than close, the wheel does not have to be true. Lace the wheel, remove as usual. Save the spokes and rim for the next time.
