There is nothing wrong with going smaller. Smaller displays can allow for more detail. Also, nothing wrong with a smaller footprint and going vertical (a great example was our summer reading display of Castles). “Smaller” can also mean not as deep. Last year’s Greenberg display was only one table (4 baseplates) deep.
Ultimately, MILS is great IF (and I stress the “IF”) it provides enhancements through terrain changes, etc. If all it does is raise everything up 1 brick and the entire display is still flat, then there is no point. I would like to see us (as a group for displays) begin to “go vertical” – adding hills, valleys, different levels, etc. Pittsburgh certainly has impressive changes in terrain. It would be great if our displays started to have some as well (not a complaint, just an aspiration).
