Here's a first attempt at a revised 'Let It Be' album, released in April 1970. I'll leave it to your imagination/own attempts as to what happens during the summer of 1969 (Abbey Road, Everest...?). The Beatles here are technically on hiatus - John goes to Toronto with Yoko and the Plastic Ono Band, does his Bed-Ins for peace, etc. He stops short of announcing he wants his 'divorce' from the Beatles in September 1969 - maybe saying something in the likes of "You do whatever you want - I'm not going to be here".
Key differences from OTL: 1) Paul doesn't push back at John's announcement, nor does he entertain the idea of quitting the band himself. 2) Paul also decides against hiring his father-in-law as the band's financial representative - whatever his decision ends up being, it is good enough for George to side with him. 3) The rest of the band ops for George Martin instead of Phil Spector or Glyn Johns to master the material recorded in January 1969. The idea of having a 'live', 'raw' album with limited studio-trickery is generally accepted, although with certain exceptions (think more 'Let It Be... Naked', but produced by George Martin in 1969 instead of Paul McCartney in 2003).

The end result is somewhat somber - while the band practiced rock 'n' roll standards and their early club material during the Jan. 1969 sessions (same as OTL) -, the final album contains very little of that (perhaps for the best, considering the dubious quality of said sessions). The 'unplugged' aspect is kept in many of the songs. George strikes big with 6 songs of his own, although many of them collaborations with Paul in terms of instrumentation - Paul has 5 songs, and John gets 3.
