I would write an E2 for this, if you haven't already figured out a solution in the last four months :P

• Spawn the E2 which will be a small cube with a green wireframe surface plane attached to it (similar to the one for Precision Alignment) and an arrow indicating which side it will copy from.
  
• Position the E2 next to the props you want to mirror with the arrow pointing in their direction.
  
• Aim your crosshair at the E2 cube, press R to refresh the E2 and it will highlight all of the props within its range a yellow color.
  
• Change the variable "Radius" in the "User config" section to change the distance the E2 will scan for props.
  
• You can reposition and refresh the E2 until you have it just right. You can use PA tool to position the E2 exactly how you want.
  
• Aim your crosshair at the E2 cube and press T while holding your left Shift key and it will begin spawning props mirrored on the other side of the green wireframe surface plane.
  
• Refresh or remove the E2 to remove all of the spawned props. You can do this while the props are spawning.
  
• After the props are mirrored and you like it, don't delete the E2 yet and save a dupe of the entire build. Then delete everything and start building from that new dupe so the props don't disappear. You can then delete the E2 if you want.

Instructions:

This just copies props, their user defined colors and materials, and the rest of their default property values. It doesn't copy user defined masses, surface properties, etc. It doesn't copy constraints. It might not get the angles right for certain entities and it could do any number of strange things I didn't consider when writing the code. So use at your own risk. ;)
