I have found that sleeping with a bug net suspended around the top of my bag/quilt can help with the temperature of the air I breath and it doesn't contribute to the amount of moisture/ice near my face or restrict air flow that much as other options can do.
My prefered bug net is an SMD Metero Bivy, but other options would work, any bivy with bug net.
I haven't tried it, but the Equinox Mantis seems like a good light cheap option.
This concept may not be warm enough for your goal, but it does help and may be one of your only options if you can't stand anything on your face.
I personally can't sleep with anything covering my nose or mouth restricting air flow.
