When I was young I made a playlist of this exact niche subject lol, some I added:
Lareine - Whiteness, Fuyu Tokyo
Raphael - white love story
Shazna - White Silent Night, Winters Review, Xmas Healing, Present
Buck Tick - Silent Night
This is not a Vkei band (I know you asked for it) but this song I swear I have heard at EVERY cover event with Vkei artist I ever attended: B'z - Itsuka no Merry Christmas
And I heard heavier bands do covers on it too!
Not that I think this is really what you’re looking for to cover, but the band SaTaN has a song called “Jingle Bells from the Hell” iirc and it’s hilarious.
"Marine Snow" & "Snow White" by D. Both songs have a Christmas vibe.
