The only thing you really need is the community behind you
1. gather the community
2. create a new thread
3. fork the cinnicoin repository
4. contact exchanges
5. proceed cinnicoin development with your new team
it would be easier if cinnicoindev agrees to hand over the thread and github repo but since it is all open source there are ways around that
As I've written on the CINNI thread, the concern, from a marketing perspective, is that, at least for a while, people searching on Google or Bing for CINNI will end up on a thread controlled (passively) by Cinnicoin "dev". No one's willing to commit any time, energy or resources to any development/marketing rescue plan that could conceivably at some point in time -- some critical point in time -- be held hostage by Cinnicoin "dev"'s absence, incompetence and/or passivity.
btw, he's been promising that his "plan" is coming "soon" for weeks, and who's to say, even if such a plan exists that it wouldn't conflict with any other plan. Just too much risk to try something new unless he's out and there's a responsive leadership team that coordinates and speaks with one voice.
