I've got a Diverge (albeit 56) and had similar thoughts on how to go touring without panniers. In the end I've opted for custom Alpkit framebag with bladder (not arrived yet) in conjunction with seatpack and if gear doesn't fit in space, I'll add in Ortlieb fork bags.
Obviously I've got a larger frame so there's a bit more space for framebag but not sure if it'll fit my bivvy bag and other stuff - on a gravel bike q factor is a bit narrower so you've got a bit less room to play with than on a mountain bike.
