How to RP a hero we with LOTD?

I downloaded the LOTD mod and I'm really enjoying it, the problem is that I want to fill all the museum (it will take some time but that's fine), but there are relics that don't make sense to get as a hero. Like The Dark Brotherhood stuff (especially the skulls), and also Daedric Artifacts... I have mods that I downloaded to get the Daedric Artifacts in alternative ways (like getting Molag Bal's Mace after killing Harkon) or destroy the thieves guild (it gives all the items). But that's not enough, is there a way to maybe RP as a Dragonborn hero? Maybe more mods that will help with the process? Because it feels weird to me and breaks the immersion that a "crazy killer" dragonborn does something like that. I restarted a new save 10 times in a week, the lack of the immersion made me stop playing for now...

Even a little help will help. Thanks 👌🏻
