My guess is that your inner tube wouldn't survive without rim tape. Don't know whether gaffer tape is a good idea (the glue tends to stick around, and I'm not sure what it would do to the inner tube) but some sort of temporary barrier between the spokes and the inner tube is probably necessary. Maybe you could double over gaffer tape so that there's only a tiny bit of glued surface to stick to the rim?
