Both Lakeview, and MFJ make brackets to use two ham sticks as a 
dipole.

While this arrangement will work very well from 20 meters up, expect 
less than average results below 20 meters due to the much shorter 
physical length of the antennas.

Also, for most quick up and down installations, don't worry too much 
about which directions the dipole is broadside too. The closer to the 
ground, roof, etc, your antenna is installed, the less important that 
becomes.

This leads me to comment on Dave's question.

The classic depictions of the pattern of a dipole is for an antenna 
that is a half wave length above ground.

Obviously, they do work at lower elevations. Otherwise, almost no one 
I know would be able to run dipoles on 80 or 160 meters.

But, if you ever hear someone running an 80 meter dipole at 120 feet 
or greater elevation, or if you ever have the chance to operate such a 
setup, you will be surprised at the difference in performance at that 
height.

An 80 meter dipole really wakes up when it is installed at or above 
the half wave point.

An identical antenna at 30 feet may produce a better signal within 200 
or 300 miles, but beyond that point, the higher antenna will cause 
people to take notice of your signal.
