BMRR, I believe you to be very wrong. I believe it to be against the company proceedures. Ask your line trainers at STN.
Again I repeat, you've never done it before, you are not trained to do it, you are not approved to do it. Blocking the runway is not your concern, you will be towed clear in 35 mins. Aircraft will have to divert. No risk to life. What a prat one would look taxiing it onto the grass at 50kts after saving the day.
