The Holy Knights to me were obviously the Tobi Roppo/Veterans for Imu, while the Elders were the top Commanders for Imu.
Because of that, I think it was always safe to assume that the Holy Knights would be reserved for the mid trio/weak trio Straw Hats along with the Revs.
While the Five Elders would be reserved for Zoro, Sanji, maybe Sabo, maybe Law, and whoever else.
Although I will admit, even I thought maybe there would have been a slight chance that Zoro and Sanji would fight Sommers and Killingham.
But according to this chapter, I guess they won't be fighting them.
