You should probably try one of these gravel/allroad type bikes with a lower bb, geo for roads/tracks maybe? I've not ridden one but if they fill the gap between a Surly disc trucker (at one extreme) and a cx racing bike (at the other) then you're sorted.
You can tour on anything but cross bikes are pretty rubbish on the road IMHO.
