It sounds like someone has done a lot of research on this subject and somebody will of put a solid case forward to the CAA for approval, whichever AA or 135 it is !
I can only say that having options for treatment of patients is paramount and if this extra 'add-on' gives the team that, then I say Well Done. Thinking ouside the box helps develop new and innovative ways of dealing with patients.
The echoes of 'It can't be done by civvies' is obviously going to change.
Well done to those who carried on fighting through the CAA red tape and came out the other side smiling.
