My idea is that the PT shoulda’ taken place decades before the time it’s set in, giving MUCH more time for history to be altered, forgotten & erased. Obi-Wan, Yoda, Vader & Palpatine are much older than they seem, staying healthy via the Force (Yoda & Obi obviously are doing it the right way, while Vader & Palps end up looking unnatural.) The Skywalker twins are created long after anikins fall, but before his chop up. The Empire itself would be much older than what the PT sets up.
I like this idea myself. Potential problem with it is that that’s a lot of ground to cover in a single trilogy.
The trilogy wouldn’t have to cover that much ground. It sets up the Empire & the Obi-Yoda-Ani-Palp relationships.
And I imagine Mother Skywalker would be much younger than Anakin?
And they would’ve met decades after the Jedi Purge?
That could be problematic, too, if it renders her a bit character.
We wouldn’t meet her. Or see the twins. Or Vader.
It all starts to come together at the end of Empire.
I could see people wanting to know who the mother is, but it really doesn’t matter to me. Plenty of room for other important female roles both old & new.
