Yup it is definitely a when not an if hehe. Fifteen times larger might not be that much bigger than the X-Wing Corvette so might be within the realm of possibility eventually.
Yup, it makes perfect sense. You still get the iconic wedge shape but it is small enough to fit into a starter set in terms of size and expense alongside Rebel scum ships.
One problem with that would be coordinating X-Wing moves with fighter token moves with Armada, but yes it would be epic.
