Why not do a partial mash with the oats and other grains.
Not sure about espresso, but I just bottled an oatmeal Kona stout that used 1/2 lb of coffee grounds. After two week in the primary, I dumped 1/2 lb of Kona grounds in a 1/2gallon growler, topped off with water and let sit 24 hrs in the fridge. I poured this through a fine SS kitchen strainer into a sauce pan and heated to 160* for bug-killing purposes. Others have said this is unnecessary, may be so, but I didn't want to chance it. Don't heat it too hot, or it may get bitter. Once cooled, it went into a secondary and the stout was racked on top. The samples up through bottling day were great. Pronounced smooth coffee with the roasted barley and caramel malt coming right behind. It is good now, but will only get better as it conditions.
