Honestly, that's not that far off from a proposed Vashoth companion I put up on Tumblr, of a Vashoth dual dagger wielder who'd provide a glimpse into life for the Vashoth, those who exist outside the Qun and never knew it. I approve of this plan.
You know what's funny? I was thinking the exact same class, right to the dual-dagger wielding.
Although I had imagined him as Tal-Vashoth, rather than Vashoth. I mean, I imagined this guy had been living under the Qun, having worked his way to go Tal-Vashoth somehow. I had imagined him to be this man who wanted to live freely, but your usual garden variety Tal-Vashoth (if I remember correctly from DA2) would go savage and wreak havoc in their path. Which is something that he doesn't want, at least, prompting him to become a solo-act.
There were other things I had in mind for him. Like his personal quests eventually crushing his natural idealism. His desire for freedom starts to isolate him- it conflicts with his want to play the hero and help the down-trodden out, because he's not as pragmatic as Morrigan is (or was?).
"Hmm, let's see- live a peaceful yet lonely existence away from everyone, while the world burns around you? Or do whatever you can in your power to help save those who cannot save themselves, even if it's at the expense of your peace of mind for the rest of your life?"
Or something like that.
I even roughly drew up a sketch of him.
I'd also like to see this post of your's.
I stopped watching after that Dear John letter fiasco.
I was one very upset little kid. 
I tried watching Zeo and Turbo. I tried. But after Amy Jo Johnson left, I wasn't as into the show. Then David Yost left, and I just stopped watching. I mean, I liked Johnny Yong Bosch, but it wasn't enough for me to keep watching. Whups.
