As for the foreach getting too long, the following layout might be useful:

foreach ( @cfgA,
          @cfgB,
         #@cfgC,   # not this time!
          @cfgD,
          @cfgE,
         #@cfgF,   # not!
          @cfgG,
         # etc
        ) {
}

But it might be easier to maintain the paths and files on your filesystem than in your script. I.e., create all the paths and files in your $local_dir; and just copy the desired paths; or perhaps tar up each configuration and untar the desired ones.
