I think, first and foremost, what is missing here is: you don't seem to have a clearly defined, actionable plan/goals regarding your solo char.
Additionally, you have unusual emphasis on jake of all trades. But that typically means your char has proficiencies in more than a few skills as well as advantages in a number of ability checks. This aspect of char building is not directly related to combat. Talking enemies to death is very situational in this game and talking yourself out of violent confrontations typically only needs to be lucky and/or persuasive enough. They are not the same as being a jake of all trades. So, how your jake of all trades fits into your solo build is undefined to me.
BTW, I spent a lot of time trying to figure out how to make a jake of all trades char for use in my Dark Urge playthrough. That's why your thread caught my attention. The above are my two cents.
