Yeah, the Jedi should have been a smaller, less known group of good-doers for sure.

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.
smoking & rambling. sorry.
