Avengers Airspace coming within the hour...promise.
But responding to my esteemed colleague's points first. Regarding DS9, I haven't ever seen it. (We're a Doctor Who household.) If the name Quarks needs changing, offhand perhaps Quantum's could work.
The question of a nativity scene in Pioneer Fields indeed did weigh on me. It seems like a "damned if you do, damned if you don't"
scenario, sadly. Though you cite Disneyland's Christmas Procession, generally the Disney Parks seem to maintain a strenuously neutral position regarding religion. Including a cathedral in Pioneer Fields (somewhat like the chapel in DisneySea's Cape Cod area) can be read as a neutral cultural element, but I feared that staging a nativity there could potentially seem like endorsement. Happily, with live annual events, it would be easy enough add nativity scenes in the future, and on a personal level that is something I would very much enjoy.
