"I am currently running a trial to test whether the crushing of bees on 
the top bars negatively effects colony buildup and survival."

When looking at other people's hives it is common to see lots of 
squashed bees resulting from one box being put directly on top of 
another.  It is easy to avoid this either by lowering the upper box 
diagonally until a smidgeon above the one below and then twisting it to 
the final alignment, thus brushing off bees that are on the upper rim 
of the lower box; or else lower it at the correct angle but offset by 
an inch or so, easing it gently into its final position.  Bee space 
usually avoids crushing bees on the top bars.
