TY Taukita!

Cool idea.  I vote B.

Hx is maybe the wonkiest part of the system.  There are many hacks for it. 

But it's useful to remember that in mechanical terms, what it really represents is your ability to help or hinder a person.  So one way of reading it would be: Knowing them well enough to predict the kinds of things you could say or do, that would either give them confidence or psyche them out. 

When you have negative Hx it might be like understanding them TOTALLY WRONG, like a Christian talking to a Satanist, or a Capitalist talking to a Communist...

I feel like added crunchiness is getting in the way of the fiction, not making it more "fiction first". 
I think a simpler solution might involve a progressive cross-off list, or a set of Conditions that can be checked (like Lady Blackbird).  In other words, don't roll damage at all.  Describe it.  That's just my 2 cents.

That said, there are lots of approaches to this, and some of them have been codified into rules or subsystems.  Check out this amazing thread: http://story-games.com/forums/discussion/19273/a-descriptive-damage-hack-for-dungeon-worldworld-of-dungeons

I had a Maestro'D who ran a show in an abandoned cineplex.  His crew consisted of about 20 NPCs, both cast and stage crew.  We assumed the back rooms of the theater had all sorts of tech and repair equipment for the theater itself (wires, cables, speakers, microphones, audio components, projector parts, screens, and stuff for fixing these things when they broke).  Since it was a big theater (ten screens) we also assumed general maintenance tools, lifting equipment, ladders, rope, etc.  So when I made up show stuff, we could just assume it (mostly) happened as I pictured it.  None of the NPCs were "savvyheads" but they were savvy at their job, which was to "keep the show running".

Of course, all this stuff *really* showed its promise when a friendly Savvyhead PC actually did enter the maintenance room.

There is no Psychic Maelstrom, but there is a move that works similarly to "Open Your Brain".  It's called "Get High".

Agreed on both counts.  In "Arresting Skinner" not only is the time limited, but it can be targeted/untargeted, and (just as importantly) its "cinematic" verisimilitude is quite clear.  We've all seen that scene in a movie, and AR is a good model for simulating it.

I have also seen movie scenes where a "Solace"-type character calmed people down, kept them from exchanging blows, or whatever, but there's so much variance here it makes it hard to determine where to draw the line.  Isn't this really just a supercharged "Manipulate" after all?
