I feel any live action Marvel series would just be limited to budget and its just not gonna get all the attention from Marvel/Disney compare to a tentpole blockbuster movie. A great writer/creative team could come up with a great 10 episode season, but Marvel Studios would probably want utilize their amazing talent for a movie, rather have them work through several seasons of a streaming series. The best series they have is WandaVision, and after that show aired, they designated Matt Shakman to a movie, rather than directing the spin-off shows Agatha and Vision.
Marvel movie stars are also no longer appearing in the shows after VisionQuest, so imagine we get a New Mutants tv series and they live in the X-Mansion, and they purposely don't show any of the major X-Men in the show.
