A few thoughts....
A) I don't see a frame-bag, nor do I see a bumble-bee-butt seat-bag. Typically these (singly or combined) take the larger-storage roles of pannier bags...Don't see either one. Both these have their perks (don't need pannier mounts), but have big cons (takes away water bottle cage space, and bumble-bee-but effects handling similar to a dog wagging its tail)
B) What is your plan to carry larger critical stuff (Tent, sleeping bag, shoes), lacking A?
C) Wolftooth has their B_RAD system:

I'm a fan of panniers myself, and you already have a hooped-rack anyway.
There are other formats of bag/rack as well, when you don't need/want the full pannier setup, but still want easy off-bike carry:
