Tom - Thanks a lot for the script! I am still straggling with aligning the two structures well, but once I will overcome this barrier I'll use it.

You first have to orient two monomers relative to each other in Chimera, for example by moving one with the mouse by hand. Then opening this script (use File / Open) will add a third monomer using the position of the 2nd monomer relative to the 1st. You can edit the last line of the script to add more than one monomer.
