AFAIK, were the Do17, He111, Ju88 operated from airfileds, which are not even on the current map, I guess same is to say for Blenheims, Wellingtons and other long range stuff. Though I would love to have a He115 or Sunderland for SAR operations, I think it takes at current pace at least 9 month to have the current content doing as it is supposed to do.
But anyhow in my opinion is the map still too small for anything having more than 1 engine.
