Hi, i was wondering .... would it be possible to somehow "join" all default CoD4 maps into one big map? .... so anybody could go to his favourite map without having to switch map on the whole server .... i m no map maker but if it's possible, someone might try to do it?

Not possible, there's a limit to how many brushes a single map can have. You'd exceed the brush count quite quickly.

And even if you did somehow overcome that limit(you won't), you need access to the source files. Which have not been released to the public.
