My club and I have done the exact thing. Yesterday we filled our barrel with an Old Ale. We all brewed the same basic beer with some extract and all-grain batches. Before filling the barrel smelled very sweet with boozy, bourbon aromas. Once the barrel was full the blended beer was great. The sample we pulled off the taste already had some bourbon flavor. I'm not sure if Allagash used this barrel or not (we assume they did). I think we are only going to leave it in there a month or two.
We have already talked about the next batch to fill it with, most likely to be a Barleywine. I think the first batch maybe two you will get some bourbon flavor but like guido said mostly oak. I think a imperial porter or RIS are both great options. Really anything that can stand some bourbon and oak would be great.
