I don`t really like the idea. When people search for maps, they typically search for map type over the ammount of players it can support. So I think, in my own opinion, that it`s fine the way it is (short having the altered melee and tower defense catagories that I wanted added). Don`t forget you can check to see how many players a map supports by looking at the info data it gives you when you click on a map`s name.
