The proto one system won't work with DCS of course. In conventional, how would you blow just one or the other whistle, and not both at the same time? Same with chuffing.
I would just upgrade to protosound 3 and not try to incorporate the original PS1. That is only asking for damage to the PS-3 board. Not trying to be negative, but there are going to be unexpected problems.
Also don't forget the PS-1 system needs a 9 volt battery to work and the PS-3 does not use a battery.
The way I thought of his was as follows:
-The Big Boy would be fully upgraded to PS2 or PS3 and run as should after an upgrade.
-The removed PS1 sound guts would be put inside a separate auxiliary UP water tender (from PS1 era) or a boxcar with center rails pick ups, and the QSI board and speaker would be located in there - totally separate from the Big Boy (which is now PS3). It could be ran behind any engine now and sound like the old PS1 Big Boy.
-A spare PS1 motor would be attached to the board, both housed inside the water tender or boxcar and not attached to any wheels....just freewheeling inside to provide proper feedback for chuffing sound when voltage is varied. (perhaps I could put a blade on the end of the motor spindle to create fan cooling for the board, but that's just an extra thought).
When running conventional, I could turn down the sound on the PS3 Big Boy tender and turn up the sound on my custom Water Tender or Boxcar with this PS1 Big Boy rig and now I have no sound conflict or crossover. Then, if I want to go back to the PS3 sound, I just reverse the process and/or remove the water tender or turn off a power switch to it so the PS1 electronics inside so they aren't needlessly frying at 18volts if I want to run PS3 Big Boy in DCS mode.
-The idea was never to have both sound systems playing simultaneously - that would be pointless. I could if running conventional, but it makes no sense.
