So, about the topic. I think that Kakashi's perfect Susanoo would slow down Guy's attack just enough for Kakashi to activate Kamui and phase through it. If Guy opened his eighth gate, I feel like this would happen:

Kakashi activates Susanoo while Guy opens Eighth Gate. Guy throws his first Evening Elephant Punch, which is slowed down by Susanoo long enough for Kakashi to activate intangibility. Guy keeps it up with Evening Elephant, throws the last direct punch, and phases through Kakashi. As he sets up to do Night Guy, Kakashi uses his double speed Mangekyou teleport to Kamui Dimension (it was fast enough to avoid Madara's attack, so I think that while Guy takes his stance, Kakashi could do it). Then Kakashi waits it out in Kamui Dimension til Guy burns out.
