I like the idea, but as the article points out, the Cuda was also announced, but never really went anywhere, and without a specific contract, I think that's a possibility for this as well.
I also like the idea of giving stealth aircraft greater magazine capacity, but wonder if it is as easy as they say. I would think that there's more to fitting more missiles in a jet than physical size, and it would require more connectors, different mounts, etc.
