Re-raw Pasteurized Milk?

If I mixed some quantity of raw milk into a larger quantity of pasturized milk, would the bacteria that makes the raw milk "raw" proliferate and re-raw the pasteurized milk? It may be a silly question, but the only raw milk that is readily available to me is about four times more expensive than the pasteurized milk I can get everywhere, so this is the idea that popped into my head as a way to possibly get more raw milk while saving myself a few bucks.
