We wouldn't be going scene by scene. I had figured on using the films as more for inspiration and universe setting.
As for characters, I had originally thought that only the Lady Solo, Lady Skywalker and Prince would be playable. However, that could potentially get confusing with so many NPCs.
So, I would say if people are willing, then the other characters would be playable too.
Yes, it would be a role reversal across the board. Lady Vader, Empress, female Boba Fett, etc...
As to post time and length, I'm going to amend and say once a week or so. If possible. Because this seems like it would be very detailed. I'm not going to set a minimum length. But as much detail as possible.
(I edited my original post, left this one as is.)
