Have you reached out to http://www.countercartographies.org/? They are locally based and might want to get involved with this initiative.
I've found this to be a really excellent example of Mapping and Design Activism out of LA: Get LA Moving complete with its own hypothetical Los Angeles Subway Map.
As part of the mapping class it could be interesting to invite the artists Justin Rancourt and Chuck Yatsuk (Racourt/Yatsuk) who are showing at Art In General right now. Their project is an installation/performance with the two artists playing roles in a fantasy of a gone awry Florida real estate agent after the housing crisis. As part of the project they researched actual and fabricated maps of Florida neighborhoods which were designed and planned during the housing boom but either never developed or have been enveloped by swamps. For example,one place is just a set of paved roads and cul-de-sacs in swampland with no homes built. Besides the performance, their research consists of photographs, video and their digital drawings and these could be shown. Link -

I meet with Rancourt and Yatsuk last week and depending on dates they are interested in attending and talking about their research within the larger class structure.
