Yes and no. Like other said, i would like to keep some limits. My thought would to use only the charm, but put a multiplier one the settlement. Sanctuary could easily keep 40 to 50 and this are BIG NUMBERS for a game in first/third person! Even Diamond Shitty has at most 30 around. But a small settlement like Hangman's Alley i can't even see the 20 live sustainable. Things i like to have in a overhaul/DLC (maybe a patch, Beth said that some patches will come with new features like in skyrim): Motoreciest ground-pump, because putting 10 hand pumps down is just silly. Fusebox, like the Power conduit just bigger area of effect. Small square fundament, like the 2x2. They would be good as a defence tower setup. If a recruit tower is connected to a terminal, being able to set a maximum number. If reached, the tower deactivates. Maybe not possible, but a way to upgrade settlers and minuteman automatically. Like from pipe guns to factory guns or from the laser muskets to laser rifles.
