Is the gallery building really a constraint at its south end? I've sometimes wondered if there is potential to put another east-west tunnel through The Mound but further up the hill. Therefore you'd have five or six parallel tracks running below the gallery. Not sure exactly how much that would gain you in terms of capacity.I don't think platform space is the primary issue but rather the approach in from the west, which the Dalmeny Chord can only fix for so long. Tracks above the current level wouldn't be possible due to the National Galleries directly to the west. Tunneling under the current lines is really the only option unless you go for a completely new station and alignment.
I'd agree that platform space doesn't seem too bad at the moment - they managed without platforms 5 and 6 for quite a long time after all. The Caledonian Sleeper loco appears to hang around in the station all day, too. Surely the line at platform 10 would be used for someting a bit more useful if space was truly at a premium.
Actually, platform 0 at Haymarket isn't pressed into service terribly often either, so the west approach may not be so busy as people sometimes assume.
