Can I use Boneless Pork Rib Roast to make "pulled pork?"?

I did this yesterday, I usually use a Boston , although the rib roast can be as good. I put the meat on a grill and smoke it for at least two hours, then I put it into the slow cooker with 1 large chopped yellow onion and a cup of apple cider vinegar to break down the fibers. Leave it for six hours, take it out and use two forks to shred it and separate any bone and fat. Put back in the slow cooker with a good BBQ sauce, something thin and with vinegar (Carolina style) in it for another three hours. Put it on a bun with some juice and you won't want to stop eating it.
