You might also talk to a machine or welding shop in your area about making you some custom width reels. An extremely easy way to do it would be to cut down and reweld some 35mm stainless reels. They would just need to know the precise spacing you require between the spirals. I doubt this would cost more than $25 per reel.
If I needed custom sized reels for short lengths of film, I'd probably take this approach. I believe I could do it with my chop saw and MIG welder, although it probably wouldn't look as good as what a machine/welding shop could do.
Maybe the S.K. Grimes shop, who I believe is an APUG supporter, could do this.
