Unconditioned Attic Insulation Question

I have an uninsulated attic that currently only has Balsam-Wool Blanket insulation (1" silver foil encased blanket with balsam wool material on inside / non-permeable). I have installed the plastic vents to allow air from the vented siffit to enter the attic freely after I add blow-in fiberglass insulation to the proper depth to reach R60 status. My question is: " Can I blow in the new insulation on top of the existing balsam-wool blanket without producing a condensation problem with regards to the "first condensing surface and proper breathing??"
