What kind of beans? I've always liked taking plain pork n beans, adding bacon, some green onions, and some BBQ sauce cooked nice and slow.
Or, there are some good 15 bean soup packages in the stores around here, to which you add a can of diced tomatoes, the juice of a lime (or lemon), diced ham and about a clove of garlic. They can be cooked in a slow cooker and they are awesome.
I wasn't too thrilled with it. I don't know, it's one of those things that isn't going to compare with the original, so I don't think they should bother. It would be like when they tried to remake Match Game.
