The messaging involved with keeping the all the local resource operations in the CIB synced across that many nodes is pretty insane.  If you are set on using pacemaker, the best approach for scaling for your situation would probably be to try and figure out how to break nodes into smaller clusters that are easier to manage.  I have not heard of a single deployment as large as you are thinking of.
