Stacking using separate random towers is unlikely to produce any useful
gain however it is great for beaming in two directions.

There's the rub...they may work.  Unless you can analyze them and
include
data for length of feedline, distance and terrain it's all guess  work.

Make one feedline 1/2 wavelength and you'll have a great local ant  but
one
that pretty well sucks for DX.  Plus, if they are more than a
wavelength apart
the "stacking effect" starts to drop.

However, it never hurts to try.

No  problem.

Just connect them and if they work as separate antennas, they  pretty
often work stacked,  too.
