Now you've got me wondering... I think that if the major pieces were vacuformed plastic, you could make the body light enough that it would be reasonable to contain a compressed air tank (fill it with a bike pump beforehand, or use CO2 cartridges), but I don't know how to regulate the pressure coming off of that to get it to fire nerf balls at a reasonable (not painful) velocity. Perhaps an auxillary 'fire' tank with a backpressure gauge that could automatically shut off the feed, but that's getting complicated....
And I wouldn't be surprised at all if the Otakon weapons policy didn't allow projectiles anyway. (quick check) no, it's not allowed. Feh.
