I'd thought of it too...trouble is, it doesn't DO anything other than put 5 lands into play, and Clear the Land is pretty weak if you don't draw Scouting Trek.
This combo is pretty amazing in multiplayer. Still, it requires some commitment to get it. I play 4x Scouting Trek and 3x Clear the Land in a Domain style deck with Global Ruin, Cromat, Draco, Spirit of Resistance, Coalition Victory, and others. Not an amazing deck, but fun to play.
