I think his room isn't that much visible in PH because they were fighting inside and he cut the mountain from the inside out. It's range is more visible when he tried to save Sanji because he had to switch with wood in order to be in a sufficient range to save Sanji, and that room didn't seem big enough to cut Noah. But yeah i think he can cut it pieces by pieces. He has 10minutes to do that after all
If it really never ends, sure why not. It slice through steel like butter which is the hardest material on a ship. And it even seems a spamable move. As for Kid it depends on how much he controls his DF yet
Zoro's tornado went through 3-4 floors at Enies Lobby and I just assume that stone is harder than the wood on Noah. Plus Zoro seems to be much stronger than he was when he did those attacks I don't think he should have a problem.
Kidd should be able to pull out all the nails with no problem, even if there were millions he pulled away close to 100 soldiers or more's guns away from them and every gun probably has as much metal as close to 1000 nails. I don't think Kidd could break the ship into pieces but he could take the support out of it and it would fall apart.
I think the guy who stole pirate flags and had the DF that made him super hot, I can't remember his name, might be able to do it. He could get close to the temperature of magma if I remember right, that should burn the ship up pretty quick. His name was Don Accino I just looked him up and he was anime only. No joke though this guy could be Akainu's worst enemy, his DF allows him to wistand the heat of lava and even eat it, he could just eat all of Akainu's lava attacks, though the strength difference is insurmountable.
Foxy could maybe do it, he'd need help but his DF allows him way more than 10 minutes. Plus his punches hurt Luffy so despite his appearance and stupid character his DF is a threat and it seems like he may have a little umph to him as well.
Oars could probably do it as well. If not Oars then a tag team of Oars and Oars Jr.
