I think the heatshrink method should work fine, but I recommend upgrading to adhesive lined heatshrink, it's a thick walled polyolefin but lined with some hot melt adhesive, stuff sticks to almost anything extremely well. It should stick to that acrylic diffuser as long as you get it nice and hot. Remember, silicone doesn't bond well to acrylic.
