Certainly a good idea.
When I played City of Heroes I noticed they use something like this for their mission maps. Prebuilt level blocks put together in always different combinations.
Plus hand-placed enemies and mission specific items.
They don't seem to stick to a rigid grid though, the tiles have different sizes and are placed at different heights too.
Their pathfinding handles it flawlessly most of the time, but they do have one of the best pathfinding systems I have seen. (I have had mobs run around 2 buildings, up a winded staircase, jump across the roofs and onto a monorail track to follow the track all the way to me while I was sniping from up there. :) )
