Buying Vacant House Included in BK7 from Bank?

Help!!!!!!!!!!!!!
I have found a house that has been included in Bankruptcy & has been vacant since Feb. 2009. It has not been advertised as a foreclosure or listed with a Realtor yet as most houses are in my area once they are foreclosed. What I am trying to accomplish is figure out an approach & way to purchase the property direct from the Bank without it going thru foreclosure or being listed with a Realtor. I have tracked down the previous Owners & have their co-operation if some form of Deed-in-lieu &/or Short Sale may work. When I contacted the Bank with a signed Authorization to Release from both Owners, as usual, the Bank asked for all the usual docs from the Owner for a Short Sale. My concern is that if I tell them prematurely that it was included in BK7 they will tell me that they don’t sell without using a Realtor. In addition, my wife is a Realtor & I even thought about suggesting to the Bank that my wife has a cash Buyer & could list the property if necessary. I need some good advice & a creative idea/ solution to avoid muddying the water so to speak & not to pay more than necessary.
Your advice & help in the situation is & will remain greatly appreciated.
Thanks,

Mr. Win/Win
