A few ounces more of down in the sleeping bag is a lot warmer and lighter than any liner around! My experience with a silk liner was (1) it wasn't any warmer than without the liner and (2) it took me several minutes to get untangled from it so I could exit the sleeping bag in the morning. A couple times of that nonsense and the liner went into the trash.

I'm having a couple ounces of down "overfill" added to my Western Mountaineering sleeping bag this winter. WM charges only $20 plus shipping for this service.
