[Endgame] What are some other key points in MCU history the team could have used for the heist?

And, more importantly, how would it have changed the narrative of Endgame?
Would it have made things easier? Harder? Would past Thanos still have hitched a ride to the future?

Just after the Snap, on the garden planet, Captain Marvel and Thor KO Thanos with a sneak attack, take the stones back to the future, un snap everyone, and then go back and put the stones back for Thanos. Thanos wakes up, headache, has no idea what happened, but still has the stones, so never suspects.

The big fight in Endgame never happens.
