If the APU fails you have 6 full applications of the accumulator mate....from 8 to 10 kts more than enough to stop.
Remembering that the accumulator is certified and good enough to stop the Aircraft from landing speeds according to Boeing...( significantly faster than 10 kts )
And besides, the APU generator is "put on the busses" and stabilized way before you "cut both" If you left it that late then you deserve a cluster f***
It's been done in the circumstances I describe many many times in 40 years on 737's 727's DC-9's etc WITH NOT A SINGLE INCIDENT ATTRIBUTED TO THE PRACTICE.
So, get a life.
Are you sure YOU are a real Pilot.
