"It would be cool to make 12 (or 9 or 6) films"

This is part of the split between Lucas and Gary Kurtz. When it was 12 (1977-1978), the idea was to have different directors take a spin through the SW universe. When working out ESB and the Revelation (1978-1979), that's when things became 9. Kurtz spoke at CV how when he was around, the third movie would have ended with Luke walking off into the sun to search for the Other. During RotJ (1981+) that's when 6 settled in, as everyone got tired of working on these projects, so Lucas tied up all the loose ends and converted it into Anakin's story. Once all that was in place, that's when the master plan stuff started coming out, it's an easy way to give the phenomenon a mystic; via a master plan.

and at any moment, a new logic can be applied and everything before can be re-written. either when he's ready to hand off the reigns to someone else, or as he goes senile, that's when things will get interesting.

feel free to speculate how to go about this.

*EDIT* Makes sense that the Holiday Special might have been the deciding factor which convinced Lucas to stop allowing others work in the SW universe. But each step along the way Lucas clamps down a bit more.

Conversely, an example of loosening up would be Genndy Tartakovsky's Clone Wars cartoon.
