Start the movie with the end of a previous Bond movie
Imagine something like the usual 5-10 minutes pre titles credits scene, 007 at the end of a random mission.. But in the final minute we see *shock* its the end of one of the previous films e.g. Dr No (the end set piece but done huge with a Dr No lookalike), or Golden Gun (facing off against Scaramanga/ChristopherLee lookalike in the fun house ) or Spy (facing off against Jaws) or View to A Kill (Golden Gate/Max Zorrin) or even as recent as Goldeneye or Casino Royale (a way of showing its an all new 007 starting his 1st mission, but Dr No probably work better for that)...
whatever film it is its be done big budget/todays FX with lookalikes as the familiar villains (not deepfake, or maybe a slight df makeover if necessary), and wouldn't have to adhere exactly there could be some twist showing a slightly different outcome (e.g. Goldeneye could show Bond diving off the dam like he did in the opening to escape from the satellite base exploding)
Then the main film starts and its the usual business of today themes/concerns/issues in a Bond film.. Probably the big villain gets hold of advanced AI and sets about building a Skynet type system..
Then Bond 27 could use another previous film in the opening and it could become a tradition.. Which old Bond film are they gonna recreate in the opening..
