Interesting idea. I would be inclined to try to make it work with existing tagging schemes rather than invent a new one (would mean you could use an existing routing application with little, if any modification).
There is not really a significant difference between this and a multi-level road interchange is there? This would mean we could use 'layer=xxx' to show the floors. The main addition would have to be a tag for an elevator - stairs are really just footpaths, and there is already a tag for them. The main problem may come in editors - how to select the correct node, way etc when there are lots on top of each other. Therefore I think it should be achievable without too much trouble in terms of the data analysis, but it might need a modification to an editor.
