Just don't make a fork, though... for heaven's sake, it's one of the few components on your entire bike that has a good chance of KILLING YOU if it fails!
This is the avenue I was thinking too. Simple would be ok... offset clamp to the seatpost or the rails of the seat and then just be a flat platform with indents for CO2, on the other side flat to hold a tyre and have two slots on each side to feed a velcro/elastic to keep it all together... that would be pretty slick.
