I want to use my VA home loan benefits to buy my wife's house?

My wife owns a home which is not in my name. I would like to buy it, pay off the mortgage using my VA benefits and pocket the difference. Can this be done?
Added (1). say the house was worth 200000 and the pay off was 90000. I can get a VA loan for 150000, no money down and no fees. Seems like a 60000 difference and payments are lower?
