I have a Perl script that I use to create matrices of schematics and
corresponding PCB layouts. The steps are ---

1. create a schematic and corresponding PCB layout for the circuit
    to be duplicated.
2. create a configuration file that defines the number and position
    of the schematic copies.
3. create a configuration file that defined the number and position
    of the PCB copies
4. run the schematic matrix script and the pcb matrix script to create
    the layouts.

Component renaming is done by the scripts. The documentation at
http://www.luciani.org/geda/util/util-index.html#matrix
has an example that shows how to create a multi-cell electronic load from
a single load cell.
