I'm sorry, but you underestimate the fodder 11. Shikamaru is a tactical genious. Neji is a JONIN and he and Hinata can perform combination attacks (Hinata also has Twin Lion Fists <--potential of that attack is unknown manga wise), Shino is highly underestimated, Sakura and Ino are medics, Rock lee has the gates, Choji has butterfly mode, Kiba has twin headed wolf. Tenten has barrage of explosive weapons.
Shikamaru with this much diversity can certainly hatch up a scheme
Also Rotation counters Amaterasu as The flames would only Target the chakra being spun around. Sakura can punch the ground bringing up debris to interfere. Tenten's weapons can get in the way.
Choji, Kiba twin headed wolf, 5 gates Lee, Shino can potentially deal with Susanoo.
The less of there victory isn't exactly favorable because of Amaterasu and Susanoo, but it isn't impossible like you wish to claim
