So... can I use that Link figurine to select him as a Mario Kart racer?

Or, can I upload my personal Animal Crossing Villager from New Leaf into that Villager figurine and bring my villager to Smash - clothing, accessories and all?

I don't think the different amiibos go across to different games. As we've already seen, there's a Smash Bros. Mario amiibo and a standard Mario amiibo.
