I don’t know… you think duplicating a spacetime volume of roughly 13.6 billion light year^3*year is easier than making a few modifications on a small scale? Note, that the ability to make those modifications is already present (teleportation, mind spells, etc).
The MWI/word splitting/etc arguments are somewhat unsatisfactory. Basically, you’re saying that anything is possible and happens somewhere. Then, you don’t even need Time Turners or any Source of Magic, you just find the MWI branch where the events happened “naturally”, and say that your story is about this specific branch.
I agree, your approach can also work, though it has other issues (it results in hard-to-smooth-over discontinuities, such as rewriting all of history to match the “new” current date). The again, maybe there is a solution similar to the original ComedTea effect.

In no version of the MWI that I know of you can communicate with the other worlds.

Why would you need to communicate? You only need to know that the right branch exists.
Also, if “everything happens somewhere” is true, then there must exist branches that look exactly as if communications with other worlds have taken place there, whatever that means.

I’m not keen on discussing the MWI much, but presumably to jump on it you need to find a way to get there somehow.
No, you just need to find a branch in which your exact copy “naturally” spontaneously appeared in the place you need.
I’m not keen on MWI explanations either. As I said, they are unsatisfactory.
