Get the latest gp 40 frame it is the same frame as the gp38-2 except the frame is milled for  a speaker in the tank already,, Then all you have to do is swap everything over install the speaker ,and sound decoder of your choice or !!wait for the B-mann to release the sound  value GP40  THAT was announced to be released in October 2014 ,but we are still waiting.Anyway you can then just swap shells since they are compatible swap.
