If you had held an emergency endorsement for 6 years, you'd know that there is more that goes on than simply talking to ac on 243, 245.1 & 121.5. Tracing action is one of the biggest time consumers. How are you proposing to put that on a GP console? There are also a host of other activities, some of which are bolt ons following 9/11, that are incompatible with a normal controlling task.
As far as GA emergencies are concerned, NATS do not have the capacity to do the task, that's why they asked the military to do it. Yes there is scope for a big change in the way that the emergency organization is structured, but you're idea isn't it. Sorry!
