It's been done and mostly comes with mods such as project Valckerie or Sim Settlements 2 . Best I find to use is a recruit mod so can you have multiple followers. They must be voiced othrwise I don't bother about it especially in a fight , and possible to change their looks. So far I have Raven Corvus from SS2 (same stand as Nora! and nice voice) Revy (she's hilarious!) , Glory . Valckerie , Heather (she's beautiful) , Eliza (raider) and with a multiple followers mod recruited , some disciples , pack, raiders (all have their own voice when in a fight) , and some travelers such as Opal and Chelsea.
