Imo i don't think thor could recreate that celestial feat as i don't think he is as powerful as he was then. thanos can levitate there advantage if they had one at all in space wouldn't be as big as you think and the odds of getting him there aren't very good either. yes it would as it's not in supes char to blitz repeatedly a char he knows almost nothing about and if you chose anti-matter because of the thanos imperative that is not common knowledge .
Why don't you answer those questions in sequence? I'm not telling you what to do, but it may help to give you a revelation. Oh and Thor is as powerful as he was back then. It wasn't all him that caused the Celestial feat. Mjolnir soaked up the worlds magnetic field to pierce the armor, and Thor amped it with his own strength.
