Sounds to me like you just wanna speedrun this, and I don't see how this favors town.
If the goal is to widdle the numbers, then I think it's going to do more harm than good. Cus let's say you succesfully hit 1 out of 5, you're now getting 1 scum for the price of 4 - then what do you sit with?
I don't know about you, but I find the odds of a PoE of 5 by D1 would succesfully identify more than 1 or maybe 2 scums.
But again it's really way too big of a risk versus the reward as I see it.
