There are no plans at the moment. I'm not even sure if it would be practical. The first seven seasons weren't filmed in HD
Some of them were. "Entity" was the first episode filmed in HD. I'm not sure if they used it consistently after that or not.
The biggest problem would be seasons 1 and 2, which used a lower-grade film than the rest. I'm afraid the details have slipped my mind.
