I really like Kevin's suggestion - and have a few more thoughts on this:
-Recently made some beef braised in red wine
(Julia Child - "The Way to Cook"). Never did this before and was impressed with the results.
Most of what I've read about brisket says that you should cook until the flat is ready, then separate the point and put that back on the smoker for several more hours. (I've smoked flats, but not whole packers [yet
]) At this point, maybe it would be a good idea to:
-Cut-up / cube the point
-Finish it by braising it (in the oven, in a casserole dish / dutch oven) in flavorful liquid
(not quite as long as a stew, because you are starting with meat that is about half-cooked, rather than just "browned") - (maybe add some pan-drippings, if you have been collecting them)
-Could add vegetables or mushrooms / onions / whatever
I also really like the idea of simmering the meat with a variety of chilis
Either way, the meat juices combine with the juices and other stuff to "create their own sauce". You could strain-off the sauce, thicken it, and then pour it back over the burnt-ends.
Sort of a "hybrid" smoky chili, beef stew, or beef bourginoine (yeah, I know - spelling!)
I'm getting hungry just thinking about it...
