The more the merrier. There is no background issue here. Most people in the Imperium are extremely superstitious and aggressively myopic religious fundamentalist fanatics by our standards, and the most pious of the lot such as Sororitas and Cawdor and Redemptionists are frothing madmen completely immersed in their faith and sacral institutions. Blinkers on and flamers lit, spouting dogma all day long. Miracles suit them fine.
Yes, but how many among the imperium have the ironclad discipline and exceptional faith needed for that to lead to tangible effects? If anything, I'd think it more likely that Cawdor gangs would assume pure coincidence was the result of their faith... Which I suppose this could still represent, depending on how it shakes out
Mechanically... Dice Manipulation is incredibly powerful, especially when it's as rare as it is in Necromunda. Unless they're a lot more restricted in use than Miracle Dice, this could be a huge buff for Cawdor.
