Can you borrow the down payment from one lender to then use to secure a mortgage with a second lender? And is that a good idea?

Looking to get into my first multi-family property (first of any type of property actually) and I don't have enough for a down payment.  Would it be possible to borrow the 20-25% needed for the down from bank A and then turn right around and give it to bank B as the down payment needed to secure the whole mortgage for the multi-family units?
