Wet Rub on Pork Butts?

Hey guys and gals, quick question: Can anyone give me feedback on smoking pork butts using a wet rub? I've used one on a shoulder I did in the oven, and really liked the flavor profile, but I'm worried about the smoke penetrating the meat if I do it on my smoker. I have a Yoder YS640, I plan on using Lumberjack mesquite blend pellets, but also have some 100% mesquite as well.
The wet rub has olive oil, red wine vinegar, and chipotles in Adobo sauce, along with a bunch of dry spices, and gets blended into a relatively thick paste. I gues another option would be to thin it down and inject the mixture then hit the outside with a dry rub.
