Suggestions for a mod often don't go very far unless you plan to make it yourself, but this thought was too funny not to share with you guys. Imagine there was a mod that makes a copy of your player character (with equipment & perks too!) and you can assign them as a settler at your base. Even have a whole settlement of you clones. Even take it the extra mile and use his (or her) voice snippets to make dialogue (kinda like the people do with the TF2 films) with yourself. https://youtu.be/_EGRT4oquVE?t=4m4s "Hello me, got any weapons for sale?"
