Yep, I think so. Part of that game, however, is a properly connected "ID" pin on the MicroUSB port. I've got a feeling this might not be the case (as the Kindle is a highly specialized PCB design, they will probably refrain to route a single connection through half the PCB that they won't likely use soon). I might be wrong here, but my experience is limited to very few tests with the K3.
Too bad that full USB host functionality still has a bad reputation with vendors of mobile handheld devices. Then, I can understand their motivation: It's basically a support nightmare, and the electrical connections involved may present unexpected behaviour for therefore unexpected usages (say, someone decides to connect his coffee mug heater with the kindle just because it is equipped with a "power cord" that resembles 1:1 a USB connection, but isn't likely to get approval from the USB consortium soon).
