If it's only 10 tiles of 12539, why bother with importing anything at all for those 10 tiles automatically and instead have those areas manually merged in? For the 100 where roads would be omitted, surely again a manual merge of that road data for those 100 would be the best solution... Then, as Tom says, you only have to share the OSM files for the data to the people who are taking responsibility for massaging the data in rather than putting in lots of nodes with all the way names attached, which appart from using up lots of space, would be a pain in the bum to connect up and in the event that roads are already there, would you want a stack of unconnected nodes all over the place that need someone to manually hunt down and delete? I could see having a copy object down to lower layer option in JOSM would be very useful for the manual merging... I know that you can already copy between layers, but, I think it's either merge the entire layer into the lower one or copy an object to another layer but not preserving it's position... d
