This is something we use frequently and it works ok the way you described now. The only variation is that we don't route the whole board but the 2 boards separately , making sure the connectors are in the same position. That is because we use a top schematic sheet which only has sheet symbols and ports plus connectors . On this top sheet, we have the sheet symbols for the 2 separate boards , each connected to its appropriate connector . After routing, we generate a new set of schematics with a different top sheet ( again we use a top sheet with only sheet symbols and connecting elements) where we delete the 2 separate connectors and connect the sheet symbol ports instead (basically the sheet symbols remain the same as in the first instance , just the connectors get deleted and the connections rerouted from one sheet symbol to the other) . The new netlist now contains the extra connections but the rest remains the same since the individual schematic sheets are the same as before and are unchanged.
