Maybe you could talk to your pastor: I don't think it could be incorporated into the Mass, but most churches I've known usually have a half hour or so of carols before Christmas Mass. Maybe that could be done in a candlelit church, with lights on for Mass -- and Christ the Light of the World!
That was just a thought -- there are people here who know way more about what's done or not done and why. Christmas might not be the day to ask -- people are mostly involved with the festivities (or for parents, maybe trying to sneak in some extra sleep after putting together toys!). I'm on my way out to our family dinner even as we speak . . .
BTW, Merry Christmas!
Nothing in the liturgy is done "for effect." The reason there are candles at the Paschal (aka "Easter") liturgy is because the Light of Christ illuminated the whole world when He resurrected.
The liturgy (both East and West) begins with a single candle (Christ) and from that candle all other candles are lit. It is a profound symbolism and at the same time literal truth being expressed in the divine (holy) liturgy of the Catholic and Apostolic Churches.
I attended the morning divine liturgy today and the Silent Night was sung after the service. Prior to the service is the liturgy of the hours and popular songs are not included.
