How far will 2 4x4 Kinos throw? Lets say I am 10 feet in the air horizontal at a 45, barndoors wide open? Will that sufficiently key light me to 2.8 on video, say 15 feet away?

You can work it out by looking at the photometric charts that Kino publish.

This gives you foot candles which is a better universal measure of light because it's independent of ISO and exposure variables.

You can then work out your exposure at that distance, but you'd have to make an assumption about the ISO of your video camera, something which is more hotly debated around here than Kennedy assassination conspiracy theories.
