I'd basically like to see a DLC or mod that allows me to incapacitate and then hack all robots in Fallout 4 and make them into companions or send them to defend settlements. If DLC, then the robot hacking part could be a perk, with there being an EMP weapon meant to incapacitate robots and stop enemies in power armor, and it could allow you to hack the robots for a free mobile turret to protect your property, or for a companion. The multiple companions could also be a perk if DLC with the limit being 4 companions. Mostly the reason I'd want this is so I could take that big sentry bot in the scrap yard around with me pretty much anywhere.
