With dual hydraulic MAX speed for diversion is 250K because of doors remain open due to gravity extension. G+Y is different because elevator is trimmed for Vapp. For a weight of 60Tons normal Vls is 130+25=155 for G+Y. S speed is 185 that should be the Vls. So you could retract to flaps zero above that and maintain at least 195kts for safety. It will be tough because higher thrust will pitch up the nose. I think Airbus needs to give more details because if you retract early you can stall. Must try this in the SIM.
