A question I've also wondered about. With the conversions from Ultras to GM or Chrysler boxes, the 56 guys with buttons have mostly been left out. Would be nice if those cars had an option.
Mr Pushbutton will have the best answer as to feasibility and what it would take on the Packard unit but in the meantime, there were some modern options I ran across when wondering what could be done. I didn't do a lot of research to see if any are readily available or truly a contender or could even adapt to the Packard cosmetics but maybe someone will.
There is one from PCS that was a relatively recent addition. It was first
mentioned in a magazine article Didn't see it on the PCS website

There were a couple of others but the links are now dead. Not sure of their status. Mooneyes had a unit that was used on several hot rods featured in a TV show over here. Wouldn't be surprised if the government found something else to regulate and they are no longer available.
