1.  Why monkey with a Dunestar box?  Coax is cheap man.  And a whole lot
more reliable.   

2.  You don't need 3 different stacking positions.  You need all or top
only.  Easily done with coax.

3.  You might want to model your situation with TA.  On my hilltop the
program says as low as 22' is pretty darn good on 10M.  Don't be surprised
if at the top of the cycle every Wooly Buger Five is beating you with
their C3's at 30'.
