If someone wanted to create their own heavily political vampire game, we (That is the former staff of RfK) would most likely be willing to help create a more streamlined version of the systems we used and pass on the lessons we've learned. We're not going to create that game ourselves partly because we want to take the opportunity to experience something different and partly because the players would expect it to be a continuation of RfK and we'd rather it be a fresh start.
Most of the systems (Boons, status, influence, feeding, beats etc) were relatively easy to maintain, the system that would have to be redesigned is the system for taking over and managing territory. The problems that became obvious as time went on was partly that time became an unlimited resource as the characters grew in XP (Actions per week should probably not scale), dogpiling became the way to get territory once territory got scarce (Teamwork should be sharply limited) and having every territory disruption handled manually by staff requires way to much work(Something more automated by code would be more manageable).
