There is a lot of options in terms of story.
You could start with Revan's story and follow Kotors path or Start before the start of the Mandalorian wars which in my mind would be far better as you could follow all the different stories and their beginnings, for example Kreia when she was a Jedi, how Darth Nihilus came to be, we know he was on Malachor V but was he a Jedi or a Mandalorian?
Anyway I think it would be fascinating but you would need very good writers to do it well.
