You've already answered your own question - it's impossible once you've applied 
any consoilidation because the values you want simply do not exist.

To get max( counter1 + counter2 ) then you **MUST** store counter1+counter2 
prior to applying consolidation.

I have a couple of things I'd like to do which have the same problem. Only I 
haven't yet figured out the best way to reliably and simply fetch values from 
multiple remote systems (and allowing for the possibility of one or more being 
down) so I can store the sum of the values.
