Have you considered suspending an inverted-L, or a T vertical, between your
Unfortunately, you're likely to have parasitic effects between any
vertical and your two towers, both of which may be resonant near 160 meters.
Some modelling is in order to better understand the likely
If you use a T vertical, be sure the horizontal part of the T is non-resonant
length on the HF bands! A good non-resonant length would be
Don't forget to use lots of radials laid on the ground, or slightly buried.
