From my research, red lyrium does grant Templars some magic-like abilities as it destroys them from the inside. I cannot say how it reacts to the blood in phylacteries, though at a guess the corruption it passes would be slower without direct contact with that blood.
I am hesitant to test this, however. As you say, there could be significant danger in doing so. I could not put a person's body at risk by testing red lyrium on their phylactery, on the chance the corruption the Red Templars experience somehow magically transfers through the phylactery to the body.
