Wouldn't the metal frame and linkages weight more than just the 2 air cylomders like in the v11

Yes. But this is rough idea, it can be improved - less frame, smaller shape, strong metal for suspension mechanism and lighter for frame, etc.

The question is how well/how much friction will be generated from translating the linear movement of the pedals (up and down) to the rotational movement of what looks like a lever arm? As the pedals move up and down, the level arm will start to pull the vertical sliders inwards towards the axis of the lever which would grind the sliders against the inner race. The S18's current suspension design with the double lever arms solves this by allowing both the upper and lower arms to pivot in relation to one another. The only down side is more connection points. Ordinarily that wouldn't matter, except KS shortcut some areas with cheap washers and low quality bearings...

Maybe something more stable like this.

Ideally there should be as less friction parts as possible. I have no experience in designing this kind of stuff.

...well, you already have 4+ pivot points there and a "pull-shock" design is probably not the best approach.

I like it but the shock is backwards. You are pulling the shock open when you hit a bump when you should be compressing. 
 

Just move the pivot to the top instead of the bottom. Doing so will also give you a longer lever push rod.

The pedals are on rail like on V11. On bump the wheel goes up and the pedals go down pulling the lever down and pushing it up against suspension piston.
