The shutter are mounted in a standard Copal 0, 1 or 3 form factor, containing powersuply and control electronics.
The major problem would be production cost and time for switching between translucent and opague.
Regarding the old electronic shutters (compur ect.) the problem was, that only the shutter timing was electronicaly controlled, using discrete components with a limited lifetime.
The rest ot the shutter was still mecanical.
