So the evac checklist you propose would have the capt select the apu on bus, then chop the engines. Whilst the FO pulls the fire handle for the APU which negates action 1.
Not worthy.
What about a boeing action to make com2 powered for 5 mins on standby power (similar to the No.2 IRS?) would prove a little more worthy than bashing carriers for not starting APU's for approach.
