I'ld go further than Simon, and suggest "don't waste your time".
MAC addresses aren't "IP addressing things", so you can't carry the
over in the way you suggest.
You have to recognize that you've chosen and implemented a topology
number of separate IP networks; your addressing plan has to fit that
and your DHCP service has to deliver addresses consistent with that
Whether another addressing plan would bring benefits greater than the
designing and migrating to a new topology (with all the likely
isn't something which anyone out on the list can tell.
Thinking "outside the box" for a minute or two ...
If your DSLAMs (I'm not familiar with the technology) and associated
equipment can meaningfully support distributed VLANs, so that you can
an extra network, distributed virtually across all your sites, then your
"problem" may magically disappear. Even if this is possible, it may
too many "interesting" failure modes. I just don't know.
