They're not released in particularly large batches and the Legends games don't have as much commitment as the main series if PLA is anything to go by so I doubt there'd be DLC.
Machamp has already had its shill moments, its simply the most appropriate Pokemon for a wrestling match of the selection of Mon available in Kalos.
It's just common sense dude, Machamp has had its time in the G-Max sun and its no Charizard or Pikachu, so there's no reason to believe it'd get any more than its already gotten.
