It's very easy through the console, no more needs to steal the fusion core. Force NPC to exit power armor: Open console, pick NPC's RefID, then type CallFunction "Actor.SwitchToPowerArmor" None , thus the NPC will exit power armor(If you use this to Ingram, you will suprisingly find actually she has legs). Force NPC to enter power armor: Open console, first pick power armor frame's RefID, remember it, then pick NPC's RefID, type CallFunction "Actor.SwitchToPowerArmor" <powerarmorframeid> , thus the NPC will instantly wear the power armor without animation. If you recieved a message that says "No script named Actor is attached to the object", you need to manually attach Actor script to the NPC via AttachPapyrusScript Actor , then use the previous two commands.
