rookie mistake, can I....

You could "try" but I'm not sure it would help. If you want, leave your wife some cold ones and you take a few and try.

It's similar to people trying to cook partially so they can finish later. The problem will be a lot of moisture has already cooked out and reheating them will affect the quality of them once you go above 165 or so and you need to go much higher to get them done more

Me? Just get some new ribs and make them fresh.

I doubt putting them in the smoker is going to add any smoke flavor to them, so forget adding wood if you do. If I were you I would put them in tin foil or cover them in a pan with tin foil. Add some moisture, like apple juice or BBQ sauce. Throw them in the oven or smoker at 250 and let them go for an hour. Start checking for the tenderness that you desire at the hour mark and put them pack in if necessary for 30 minutes or until they are how you want them.

As for my SL ribs I am at 250 for 4 hours and mine are almost always done at the 4 hour mark. You will get it right and probably on your next rib smoke will feel better about the results. Keep it simple until you get it down, and then start with all the "tricks".
