jobs and experts and including projects

Hi, I love jobs and experts but I want to use the plugin in a different way. I want to keep the expert part but want to use the jobs part in a differently. I want experts to post jobs (projects) they workED on in the past so that they can showcase them. I want to link them from their expert page.
So instead of posting new jobs I want to publish old projects. Is this feasible? How hard will it to make changes or is it only a matter of renaming (text)fields?

Thanks for any thoughts!
