Yes, agreed. I don't know why I forgot about that option.

Merge can be very slow with a high number of objects though, so if a 
semi-transparent path is desired, sphere_sweeps may be faster after all, 
though I haven't compared results myself. If a semi-transparent path is not 
needed, union should definitely be used rather than merge.
