I feel like they're in a spot where they cant reboot anything except Inhumans without throwing everything else under the bus, and that's gonna be a bad move. Endgame got Jarvis on board, Agent Carter connect to SHIELD, and from what I understand Cloak and Dagger also picks up plot points from AC, C&D now has connections to Runaways and Luke Cage, Luke Cage then has connections to all the other Netflix shows. Inhumans is the only one that's pretty self contained.
Avengers: Endgame featured Edwin Jarvis from Agent Carter, therefore that show is 100% canon. Not just the character, but the same actor. The end of Season 1 features Arnim Zola, and the Hydra theme from Agents of S.H.I.E.L.D. plays. The Dark Force that was introduced on Agents of S.H.I.E.L.D. made an appearance on Agent Carter. It became the source of Cloaks powers on Cloak & Dagger.
Agents of S.H.I.E.L.D. features Nitramene from Agent Carter. Agents of S.H.I.E.L.D. features a reference to the events of Daredevil, specifically a gang war, on a TV. It also features a Judas Bullet from Luke Cage, believe it or not. Micro from The Punisher helps out Coulson's S.H.I.E.L.D. in Season 2. The Dogs of Hell biker gang appeared in Agents of S.H.I.E.L.D., Daredevil and The Punisher. WHiH Newsfront references the ATCU from Agents of S.H.I.E.L.D. and direct events related to them.
Metro-General Hospital, which was introduced on Daredevil and used in other series, made an appearance in Doctor Strange and was mentioned in Avengers: Endgame, although it was a separate facility.
Inhumans references the Terragen in the water supply from the end of Agents of S.H.I.E.L.D. Season 2.
Runaways features a news reporter from Agents of S.H.I.E.L.D. and an obituary for an agent from the pilot episode.
Cloak & Dagger references both the movies and the Netflix shows, as in one episode "keeping up with the Jones" becomes "keeping up with the Starks and the Rands" and O'Reilly was friends with Misty Night from Luke Cage. She also knew Ben Urich from Daredevil, as evidenced on season 2. Luke Cage was referenced.
The Netflix characters were considered for Avengers: Infinity War.
Black Panther and Luke Cage were both going to have Tilda Johnson/Deadly Nightshade, but once Marvel knew Luke Cage was going to use the character, Marvel Studios changed the name of the Black Panther version of the Character to Linda. Kevin Feige confirmed that Tina Minoru in Doctor Strange was just an Easter Egg, as not to conflict with Runaways, thus claiming that Runaways is canon. Captain Marvel uses the same quinjet set from Agents of S.H.I.E.L.D..

Also why would you get rid of a perfect Daredevil? The show is literally better than the films, it would be crazy to replace him with something less than.
