I don't know if it is technically possible but someone might be able to fit it inside a microSD body (microSD being 15 mm × 11 mm × 1 mm). It might even be possible to make the card do double duty as a digital compass plus memory storage.
This isn't plumbing you know. It's not only about fitting it, it's mostly about integrating in the circuit. I somehow doubt the AKwhatever will be able do directly 'talk' to the memory controller that manages whatever is in the microSD slot. And i'm pretty sure it's simply not possible to plug something into the mainboard without having extensive knowledge about how it works. The chances you'll not break something in new and interesting ways are pretty much like winning the lottery
