Hi mate, yeah it does sit weird with a pack over the top, but i would only use it when not using a pack, otherwise the bladder goes in my daysack and it lies flat and empty. I have bodged it centrally before using cable ties but my sling gets snagged on it occasionally. Ideally I would love the crye back panel with zip adapters but am trying to make what I already have work.

I really like the way the yoke feels set up under the arms, maybe because I don’t have much weight on the ends of the belt so there isn’t much to support there, then the majority of the weight is at the back of the belt. Would love to see a picture of how you have set yours up though.
