If the chassis surgery required to install the Borg-Warner is simply 
more work than the guy wants to entertain, and no modern equivalent is 
suitable, I'll throw out a couple of wild-assed guesses on other 
options--a decent fab and machining shop could probably adapt the 
working bits of the VW automatic stick shift to the car.  Would likely 
require some welding and modification to the bellhousing to fit the 
solenoid and some modification of shifter extension for the switches, 
but it could probably be done.  A similar--and less invasive--approach 
would be to use the existing bits, except to substitute one of the 
hydraulic clutch throw-out bearing units currently in use (Herman?) and 
then find a suitably-sized electric or electric servo piloted 
vacuum-operated solenoid to operate the clutch master.  A Spitfire 
shifter arm with a knob-mounted clutch switch would, with a little 
practice, make shifting almost indistinguishable from standard.
