First make sure there is weather stripping between the skylight frame and the curb, assuming this is a curb mount. sometimes there is not a seal inserted at that joint. If that is not an issue, then you could certainly install a frame around the well at the ceiling level and insert a piece of clear acrylic to keep cold from dropping into the room. I have done this at a previous residence with great success. Good luck
