As pointed out the numbers just don't work. You'd likely have no one to race against in your local crit.
Unfortunately, there are more and more amputees with Afghanastan and Iraq, so there may be enough numbers out there, if there was a venue. Thus it may be that there could be para category added to some larger regional and national races, where you might attract enough people to have a decent race.
I would talk to the organizers of the bigger races in your area, as well as talking to the other 20 licensed racers and see if you can drum up some interest.
A few years ago, the Jacksonville race when it was on the NRC calender put on a handcycle race on the crit course. I'm thinking you're going to need something like an NRC event to be big enough to hope to draw enough people.
