Sure, he would have to find the right opportunity. If he can get a KD, obviously that would be the best but it could be off the clinch or in a scramble, a naked shot on Jones probably won't work. And as far as Tom gassing and Jones not gassing, we have no idea if that's true. Just because Tom finishes fights in the first couple rounds doesn't automatically mean he's going to gas in the third. Also, because Jones has had good cardio in the past doesn't mean it's still true as an older heavier fighter. If you noticed in the Stipe fight, he only grappled one round and his grappling even at LHW was becoming more and more scarce to the extent that he only tried one TD on Santos had to panic wrestle against Reyes after getting lit up on the feet for 3 rounds. I'm not sure he has the cardio for a grappling-intensive fight at HW. He can try to tire Tom out but I have a feeling he will also be tiring himself out.
