I am firmly in the "one sch <=> one PCB" camp myself. So if it was me I would copy and paste the schematics until I had the division correct, then I would have to manage two sets of manufacturing docs and test docs etc etc but I would still do it. The additional overhead over what the combined assy would have taken is not great - there is the same number of components (or close to it) and the overall complexity is not much greater. But that is just the way I would do it - maybe a smart panelization and clever layout will work for you.
