Hi Rhaul: I asked the module maintainer of referencing to help point you in a good direction. I had to do some referencing work a while back and took some notes here: - http://docs.codehaus.org/display/GEOTDOC/Referencing+Developers+Guide
There is a helper class called CRS that can help you build things; but it mostly delegates to all the factories and authorities and so on talked about in the link above. Chances are there is going to be a factory that needs to recognize the words "Polyconic" and produce an implementation of a projection class of some sort.
