Having not gone on the scout it's hard to really judge the best route to take.
A cheep route would be a 2 or 3 12K maxi brutes. Put them on 4 riser avenger cranks and space them to put slashes Thur the woods aimed right to left. Put a frame of full blue in front and WaLa. If you could get a couple of condor lifts that would be better then the avenger stands. They can get much higher and are safer. I am assuming their is room in the woods to get the units in place.
You could just use the 6k and 18k as well (get the 12K cinepar if you can. Its easy to reduce light but hard to squeeze more out of a small light not that the 18K is small). Using the avenger cranks or the condors do the same thing as you would with the maxis. Now you don't need blue, but you only get 2 slashes instead of 3 thou.
If you want an ominous look put the 6k way down the path and off to one side or the other shine it right into the lens. It puts a neet affect on all the branches and is motivation for any other back light you may use in the sequence.
The HVX likes a lot of light. If you want to reduce the intensity in post its easier that bring the level up in post.
Talk to your Gaffer. He/She may have a way that looks great and is logistically easy as well. Use a Seasoned Gaffer and Seasoned Key Grip rather than a school chum. This is not simple and it will take time to set up and keep SAFE. Bring your chum along for the show :)
