Will Walthers or Branchline do Pullman 'betterment' cars ?

Now that a lot of the basic common cars are done will these companies consider the Pullman rebuilds or 'Betterment' cars.

I would like to see the 6-6 'Poplar' series the 8-5 'Clover' series or the 10-3, or 12-2-3 'Elm'. Some of these cars lasted in the Pullman pool till the 1960s.
