Editing Battle/Friend Passes in Battle Revolution

[TrainerSpagh]

So I've been really into salvaging lots of old lost pokemon from childhood saves, and lately I've been messing around with Battle Revolution specifically.  One of my friends lost a game ages ago, and I discovered that his old party is still in my battle revolution save as a friend pass, complete with his long lost charizard from childhood.  Is it possible for me to edit/extract pokemon from passes directly?  I've been using PKHeX, but it doesn't seem to have any options surrounding passes, nor am I familiar enough to grab it directly from the save with a hex editor.

 

Thanks
