Is this Octopath Traveler art subtly hinting at a Bravely franchise connection?

This can't be a coincidence, can it? On the right-hand side of the picture above, you see the artwork Square-Enix released today to celebrate 1 million units shipped for Octopath Traveler. On the left-hand side, you see Airy from Bravely Default. The two pieces of art are completely different, but the silhouette of each are pretty damn similar! Is this a sly tease of something in the works, or are people looking too much into this?
