Really?
And, of course, the controller side of the glass must look, act and feel exactly like the current operational system. Otherwise you will impose flow due to controller unfamiliarity with the 'new' backup system.
Having been closely involved in 'backroom' work at Swanwick this doesn't sound like the VCCS (Garrex) system that failed. Not having worked there for 2 years I'm not going to speculate further.
