That is to 100% your headcanon and let us not forget that Zetsu saw the CM State 2 already during the fight, why should he surprised of Sasuke using CM2 now?? That makes little to no sense. He was clearly surprised from the Susanoo as it's the only thing he never saw before, while the Curse Mark was seen pretty often.
 * "The fact that Zetsu questions what Susanoo is after Itachi uses it a 2nd time meams that he didnt see it activated before Kirin launched. If Kirins travel time is 1/1000th and no one seen Susanoo before its launch then Itachi activated it between launch and contact."

That makes already half of Itachi's reserves gone, meaning that he can just use 1,5-2 times his MS abilities xD Shadow Clones divide the chakra equally between each other. We saw Itachi already being out of chakra after a Tsukuyomi, Amaterasu, a fireball jutsu and a few illusions... A shadow clone takes way more chakra than these jutsus.
 * "Itachi creates an exploding shadow clone as Minato moves in for a FTG Slash and it explodes, but Minato FTG's away."

Bye bye chakra. Itachi can use his MS by now just like 1 time, maximal 2 times with his state becoming worse through his sickness.
 * "Itachi will try to Amaterasu him but he is too fast and will more than likely stick to his blind spots."

and where does all that chakra come from?? Itachi's reserves were already worse than average, the sickness made his reserves even worse. His Susanoo usage is bringing him already to the brink of death...
 * "After another FTG Slash Itachi activates Susanoo and goes for a Totsuka seal."

and that is where Itachi has no chakra left anymore. He is out of it... Let's not forget that Minato's Shunshin would be enough to avoid the Amaterasu, the Yasaka Magatama and even the Totsuka Blade. While Minato could keep tagging area's without his Kunai's and misleads Itachi by making him think that he can just teleport to the Kunai's... The same way he did to Ay.
 * "Minato either imediately pulls back or gets knocked back but ultimately avoids getting hit by Totsuka. Now Itachi begins spamming Amaterasu or launches a Yasaka Magatama."

This isn't even within the possibilities of Itachi anymore, as he passed his limits already. He hasn't that much chakra dude, this was made pretty clear. Itachi would have killed himself and Minato would have survived by your scenario. You should count how often Itachi was able to use his MS against Sasuke and what kind of reserves his jutsus used up... The exploding clone uses shadow clones and that uses half of Itachi's reserves, something he doesn't have much of.
 * "In the case of Ame, Minato simply runs. Itachi ignites all the kunai he can see so Minato uses shadow clones to close the gap. 1 clone FTG's Susanoo away while the 2nd goes for the kill and marks Itachi in case he manages to survive. After that its a repeat of this process until Itachi dies of exhaustion or Minato FTG Level 2's him."
