WAL is not the bottleneck ... as I already mentioned today, pg_clog (and
more specifically the meaning of transaction IDs) is what really makes a
cluster an indivisible whole at the physical level.

If you want to do separate physical dumps/restores, the answer is to set
up separate clusters (separate postmasters).  Not so hard, is it?
