I don't think doing doing multiple anchor phases is the way to go here. For one thing, that particular program is not meant to maximize your strengths gains (as stated in the book), and for another it's generally not recommended to stack anchors together.
I'm also doing the same program, but I'm just starting phase 2 so I'm six weeks behind you. Did you check out the Fat loss/Prep program in the new book? It's very similar to Krypteia but with different and more variety in the accessory lifts that are done in the same manner as Krypteia. Just a thought if you like that style of training.
