Why put it during the time of Revan and Malik to begin with?
You have plenty of space to breathe in The Old Republic, it was a huge span of time.
By tying yourself to that period in time you are restricting the story /and/ making huge FC's/NPC's again.
So you are adding problems.
I would go for a time period some 1000 years or so after The Old Republic (Bioware's MMO). You could create whole new threats, leave the game wide open for whole new heroes (PC's!) and you have complete creative freedom to do whatever you please without upsetting traditionalists.
