Only if you could recover pieces of dead Taken Vex. The problem with that is that when you kill taken enemies, they get pulled back to wherever the were pulled when they were Taken. Somewhere in the game it mentions that the Taken don't die, they just return to where Oryx made them. That being tbe case, there'd be no physical taken vex parts to recover and use as armor. Now, if the vex armor contains vex consciousness like the ahamkara armor pieces contain the essence of the worms, then it MIGHT be possible to use a Taken process on it, but i think that theory is a bit of a stretch.

Im saying the vex armor is alive already. So it becoming some form of taken armor makes sense.

The thing is though, we know the armor infected Kabr. But was it the armor itself that was alive, or did the living fluid from the mind cores seep into the armor? It's an important distinction that we just don't know the answer to.

Either way something is alive right?

Not necessarily. That's a pretty deep question about the nature of life itself vs. collective consciousness/artificial intelligence. That discussion is probably too much for the forums here, heh.
