Even though it would be slightly more expensive than .22lr it would be nice to have a more powerful round available that can be bought extremely cheap and in bulk.
What makes a cartridge cheap? Amount of material used? No. If that were the case, 243 ammo would be cheaper than 308.
One of the costs of ammunition is setup/changeover time of the multi-million dollar equipment used to produce ammunition in high-volume manufacturing sites. 22LR is cheap because of the volume manufactured. The equipment runs pretty much around the clock, which makes it cheaper to run than short run, stop and start products. 22 Short used to be cheaper than 22 LR because it uses less materials and there was sufficient volume to keep prices low, but 22 Short is getting expensive since volume is now so low. Last box I saw was about $5.
One of the most successful gun product launches of the last 50 years was the 17 HMR. Manufacturers made rifles for it, ammo manufacturers made ammunition for it, and it was all well coordinated (which you would expect, since the 3 main participants were Hornady, Marlin, and Ruger, an ammo maker and two gun makers), so they had immediate volume. Remington could have had a similarly successful product launch 43 years ago when they launched the 5mm Remington Rimfire Magnum, but they flubbed it.
And to answer the hidden question or assumption in your question, 32 RF would not be more powerful, due to the concerns about the fitness of older firearms (see 7X57, 8X57 threads).
So, why would anyone bring back a product that has been obsolete for 20+ years, incur all the product development costs, buy new equipment,develop new firearms (all this in the middle of a recession), and incur all the liability costs of some dufus sticking one into an old BP 32 RF gun and blowing up his hand?
