I believe that if you taped or glued the flameless candles to the bottom of the lantern and somehow secured the star/tree topper base, and maybe did something different with the ball ornaments before adding snow, you could do it!

Then you could just lightly jostle the “snow” filled lantern with the tightly glued star or nativity scene and make it the aftermath of a beautiful snow storm inside! You’d put just a few inches of the snow in the lantern.

Naturally it wouldn’t snow like a real, liquid filled snow globe, but it’d still be fun to make the drifts of snow move around.
