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.
