There are still 12 seats left from Chur to Brig, but you would have to re-design your itinerary to make this work comfortably I think. It would be a very long day from any of the towns you mentioned, see "Don't have time for the full route" on www.myswissalps.com/gl acierexpress. Personally I don't think it's worth it from your base towns. I would focus on things to see closer to where you are staying. Days are very short late December. There's sunlight only from about 8 AM to 4:30 PM, so long days of outdoor sightseeing are not possible.
Another option is to take the regular trains as explained on the page I mentioned. It won't make the trip shorter but you'll be more flexible time wise, and it's cheaper because you don't need reserved seats.
Note that Brienz, Murren, Grindelwald and Interlaken are all very close together. Personally I'd stay 5 nights in one of these towns to save time on moving hotels. You could travel from Lucerne to Chur, then take the Glacier Express to Brig and switch for Interlaken if you really want to.
I hope this helped :-)
