The 4 intelligence is kind of a dealbreaker for me. I do not play a BoS character with lower than 6 int. 9 is recommended. The one I run actually has low agility and luck because it's a low VATS build. Combat is close to mid range. for the most part, though I rock a laser musket in case I need to do some manual sniping. Granted, this is a specific challenge run, and I salute you for it.
Another outfit you probably could have worn could be the BoS Scribe outfit(the Grey one, not the Red Field Scribe outfit) as its probably the closest thing you can get to the Outfit he wore as a Squire.
awesome video, though i cant tell if i'm being weird or if the framerate is sorta low sometimes otherwise great vid(PS. I don't know if its nexus only, but theres a voice changer for the power armor)
