There's a dummy script at http://repo.or.cz/w/ump2osm.git/blob/HEAD:/osm-merge to do that (would need to be modified for >2 layers). The bug mentioned there has been fixed and I though josm now does something clever on merging, like merging nodes. BTW I have always strongly discouraged doing big uploads with josm as it always dropped them on the floor on network errors in a way that doesn't let you recover and continue from where it broke, being one of the main causes of people needing to do reverts and spamming db history with deleted nodes. It may have gotten more clever recently, not sure.
