If Metal Spin comes back

[lhii789]

It's been decade since we last saw Metal Spin in Stage 2 (SASUKE 27; 2011), where it was replaced with Backstream in 28 and beyond.
Despite Inui (director), is the one who removed/rid of the obstacle, what if Metal Spin make a sudden comeback, regardless if it replace Backstream (which is unlikely) or take place between Salmon Ladder and Backstream.
I would like to see how Morimoto, who previously attempted it in 27, would confront it this time.

It certainly won't replace the Backstream since that's Inui's baby, but I don't see it going anywhere after it since as we all know would just be asking for a bloodbath. The real question is where would you put it? And I honestly only see it being before or after the Spider Walk, but not after the Backstream or before the Salmon Ladder.
