Marty makes a good point. Ultra high temps, moisure and pinched wires are what kill probes, so as long as you take care in those areas, that will definitely work.
But if you do want to have one mounted, make sure you have a good sharp drill bit and cover the spot with two layers of Frog tape front and back to keep the finish from chipping. Use a couple of stainless steel washers with it. I would recommend mounting it on the opposite side from the vent. I mounted a Weber Q thermometer (7581) on a 18.5 inch kettle in this manner. Make sure you get one with the shortest stem length you can find if you are going to mount it this way. Here
is Tel-Tru that would also work.
