importing and merging caches

A related question to Felix' issue, just for my interest.

I wonder if it's possible to merge two existing caches on two different computers that are
not necessarily connected ?

Importing sites on a wwwoffle should be no problem with wget.
But how to 'spit out' all the conetent of a cache in a form that can be fed to wget ? 
So that it even works with a dvd transfer ?

ok, here's my quickshot:
Say, we are to merge the cache from wwwoffle (A) on one computer into the wwwoffle (B) on another
machine. 
We set up a second new wwwoffle instance (B') on (B), and copy the cache (A) to wwwoffle (B').
Then fetch from (B) anything stored on (B'), recursively.

Sounds complicated, though. And is it possible at all ? 
And how exactly fetching 'anything stored on cache (B') ??

Perhaps one of our commandline artists got idea :) ?
