I don't believe they're taking that direction, but after reading your comment, I instantly thought of a mix of magical elements and force projection.
There's also this, straight from the opening crawl
But in the dark corners of the galaxy, a powerful few learn to use the Force in secret.
Which we can always tie to this:
Which would really open Pandora's box of what could be possible. I've trying to concoct some sort of theory like what happens in "Us" about Mae and Osha perhaps being switched, or switching themselves even, but I can't really come up with anything plausible, other than this:
Osha figures out what happened on her planet, and that the Jedi were to blame.
She leaves the Order
She goes home, finds Mae, who is happy and healthy and doing whatever.
Osha somehow mind wipes Mae and takes her place, convincing Mae she's a Jedi Padawan who left the order to be a mechanic
Osha (now calling herself Mae), already having all the Jedi training, now goes in search of someone to help her get revenge on the Masters. If you combine 10 years of Jedi training with x number of years under Deep Voice Sithy McSithSith, you've have a pretty formidable warrior.
But it's a huge stretch.
