It’s a nice idea that each is sort of a pillar or slot that needs to be refilled.
I guess Science Wizard: Ironman to Spider-man
Power House: Thor to (in the comics it would be to Thor Female) Captain Marvel
The Captain: Cap Am to The Falcon, but he changes his name.
And the Monster? Hulk to Ant-Man? Idk.
As far as I know right now the list is this: SM2, GoG 3, DS 2, BW, BP 2, AM 3, CM 2, and probably MoonKnight at the end. And that starts very soon, because Spider-Man is in…July?
Also we have those Fox X-Men movies, Dark Phoenix, New Mutants, Deadpool 3 and finally Gambit.
(Mind the Sony Spider-Man spin-offs, Venom, Morbius, Venom 2/Carnage, and that 3rd unnamed movie that may never see the light of day. )
Then eventually the reintegration of the X-Men and Fantastic 4 into the MCU in the toward the end of whatever this next wave is named.
After that, I am not pretty sure about what happens, there is probably going to be a Namor as a villain movie, probably in the Fantastic 4. Maybe a She Hulk movie because it would be good to add some more femme power. And probably Nova or Kamala Khan being introduced officially as characters without their own movies a la Vision and Scarlett Witch.
I doubt they would take a bet on Daredevil or Jessica Jones or anybody on Netflix or whoever has had a movie like Ghost Rider again.
