Can this ever work in town's favor?

I'm not sure that this works out to be advantageous. Imagine a setup of Cop/Doc vs. RB in a standard 7/2 format. Mafia is can look at who is targeting whom, and make an educated guess of which players are softing doc and which are softing cop based on their target choices. They know whether they will be targeted at night and could plan to RB whomever may be investigating them. They know all potential targets for the doctor, and can choose their NK in such a way that the doc never blocks the kill. What does Town get? If the Cop flips, you can look at her target and guess that maybe scum was trying to prevent them from being investigated, but that has built in WIFOM because mafia can conceivably target players for the explicit purpose of setting this scenario up.

I think in this scenario, it might be better for everyone to say "If I was a cop, I'd target A, and if I was the doc, I'd target B". This makes it harder for scum to isolate the cop based on false positives from Townies.
