You are right up my alley...like the way you think!!! That's the way I would do my bbq place as well!!!!
Interesting thought.....my brother and I actually have a barbecue team as a hobby, and cook in a couple local small competitions each year...nothing sanctioned by the KCBS yet, however. I also do some occasional catering for family and friends.
If I had a joint, it would be traditional, serving the best meat and homemade sides I could come up with. The importance of good barbecue is first and foremost important, and here in St. Louis, people put too much emphasis on the sauce, which I think is secondary. Regardless, I'd have to have a decent sauce. One alternative to the sauce chase, though, is an approach I've seen in a place in Kansas City---they offer many different sauces, of the diner's choice, and feature one or two each month. It gets them out of worrying about the sauce, and allows them to feature local or regional makers of sauce only.
Bread is also important to me....one local place here in St. Louis serves garlic toast with their barbecue...not to my taste. Plain white bread, please.
I'll echo others' comments on the sides....they have to be top notch...I hate baked beans that are too goopy, or potato salad or slaw that is dripping in mayo, fries that are cold and tired, etc.
Any good joint also has to have a side dish or presentation that they are known for....think the fries at Arthur Bryants, cooked in lard (yum). Hushpuppies or stew at the NC joints like Stameys in Greensboro. The Rib and Fry plate at McClards in Arkansas. The beans at Jacks Stack in KC. The onion rings at Sonny Bryans in Dallas.
Also, offer cold beer and a decent homey dessert like cobbler.
