Perhaps host the Sentinel group different to the others. I understand each group is based on a ranking system. Rather, I'd enjoy seeing the sentinel group based around a profession system. Sentinels typically worked alone but still adhered to the council. Here are the following Jedi Sentinel professions as per Wookieepedia;
Jedi Investigator
Working as specialized trackers and even spies, the Jedi Investigators worked closely with law enforcement to track down criminals and discover the truth behind crimes. Going undercover for long stretches of time, investigators should not be confused with their Shadow cousins, as the role of an investigator focuses mainly on crime as opposed to Dark Side Adepts.
Jedi Recruiter
Working as members of the Acquisition Division of the Order, the Jedi Recruiters honed the talents learned from Jedi Investigators to track down and identify Force-sensitives to assess whether they belonged in the Jedi Order. Republic law required all newborns undergo testing, with potential candidates' names being recorded in the Division's prized Kyber memory crystal. After the child had aged a few months, the Order would dispatch a recruiter to test the child and see if they met the qualifications to begin training on the Jedi Path.
Jedi Shadow
A highly respected and secreted group of Jedi, the Shadows went farther than the Investigators in their hunt for the truth. Working closely with the Council of First Knowledge, the Shadows seek and destroy all traces of the Dark side of the Force, and its adepts. While not always present at the Temple, the Shadows were based in the Temple Precinct and reported back as frequently as their mission allowed.
Jedi Watchman
The Jedi Watchmen were a group of individuals who chose to work alone in the oversight of peace on a single planet or system. Focusing on bettering society and protecting the rights of a system for years at a time, they became a vital liaison between the planetary government and the Jedi High Council.
