Refrigerate until firm; unmold.
Ice 2-layer cake (3 in. high) lightly with buttercream. Prepare 2 1/2 recipes of ganache glaze and cover cake; let set. Place cake on foil-covered board; dowel rod cake where plaque will be postitioned. Pipe freehand snowflakes on sides with melted candy in cut bag, piping 3 intersecting lines with "v" shapes at tips.
Position candy plaque and chocolate vein insets. Position 6 white veins on cake between petals; attach 6 to plaque at petal intersections with melted candy.
