Sure.
There's no truly breaking strategy, but there is a slight optimization.
At the beginning of each day every living player should make a post that says "If I am Bus Driver I drove X and Y. If I am cop I investigated Z and they were M." You can overlap your claims as much as you want, but you should try to keep them reasonable to what you would do if you were bus driver or cop.
Power roles should claim if:
It is the day before an elimination can potentially end the game.
They have been run up and are about to be eliminated.
A bus driver gets an innocent result (this means that they targeted X and Y and Y died, therefore X was the scumkill target and thus town).
Neither bus driver nor cop should publicly hint at their targets before the night, nor should we as a group try to target them. Bus driver should focus on being a vig because changing a kill is very much so positive utility.
The setup is within an expected win rate of 40-60% for town when simulated with random eliminations (probably closer to 60 than 40, although I don't remember what the numbers actually were and would have to dig through two years of mafia bullshit to find the program that gave me the numbers).
