The Pans-Ops criteria, nor the FAA 8260.52 consider Engine Out in the procedure design. The missed approach is based on a minimum performance gradient.
As you noted, the criteria nominal climb gradient of 2.5%.
This is a gross climb rate of about 227 feet per nm.
The net climb is about 167 feet per nm.
Check with the performance people...but EO performance for 2 engine aircraft is along the lines of 100 feet per nm depending on temperatures/loading, and I have worked extensively with 65 feet per nm.
EO procedures are separate, and, to date, custom designed.
Most regulatory agencies do NOT want EO procedures in the public realm, and want to direct the aircraft as able.

Re yr post #21: The Thirteenth Meeting of the Obstacle Clearance Panel (2003) added the following to the Foreword of ICAO Doc 8168 (PANS-OPS) :
Quote:
1.5 The design of procedures in accordance with PANS-OPS criteria assumes normal operations. It is the responsibility of the operator to provide contingency procedures for abnormal and emergency operations.
