I mean I was thinking of a epic story of a Jedi who thought he was weak compared to he prodigy of anakin but is trained by a certain master, even after he leaves the order... publically has another master but he and his old one have a plan to overthrow sidious in a Jedi fashion and to stop the war... The main key to this Idea is the real theory of dooku being a double agent his entire time during His time as a dark Jedi.. don't see him as a real Sith.
He Went to soreno and was the only jedi let in, snuck away from his master, who he was also very close with to train with dooku, even up to the period of season six of the clone wars in canon. He considers master dooku and tyrannous different entities, like what Vader would be to anakin and dooku only acts like his old self around this by then, 21 year old by episode 2, He had known and largely had even raised him before he left the Order when this character was about 11.
Just a concept, not saying more to keep things interesting.
