BBQ cook off this weekend thinking boneless ribs.

I have a BBQ Cook off this weekend at a private club I belong too. Had it all worked out I was going to use Hog Wings, BUT Gordon foods quit carrying them. So kind of in a pinch and was thinking about trying boneless ribs. Never done it before but my thoughts are buying 4 or 5 pork tenderloins "not loins" and cutting them in half long ways and pounding them out a little to get a uniform thickness and then putting the shish Kabob sticks in. Then toss on the grill till ready. Figure it would be quick and easy. Has anyone ever tried this? And do you think the tenerloins might be too tender to do this with? Any advice or alternate ideas would be appreciated! Let me state first, these guys are not BBQ type of people and all they care about is if it tastes good. If it was boiled or had a bottle of liquid smoke on it they probably would not even know. And we are doing it on small grills in the parking lot so its not going to be anything overly fancy. Start grilling around 9:00 or 10:00 and everything has to be ready for judging by 12:30 before the football game starts.

Well I was actually probably going to do most the cooking at home and then throw what I make on the smokey joe to reheat and bake the sauce on. I'm not the best with ribs and the 3-2-1 method people use on here would have me starting earlier than I would prefer to get there. We never discussed how much, only rule they made that I was against that what ever you make HAS to have BBQ sauce on it.

Also I was thinking the Pork Tenderloins because when I cook them whole I pull at about 150, when they are still a little pink in the middle. So I figured if I had about a 1/2 inch or so of boneless I could pull when they are still moist and they would only take 10 or 15 minutes so I would not have to dry them out. Might have to buy and try it out for a practice run
