Ok, I just checked the manual for the L plate - RTFM, I know - and they explained that you can move the camera forward or backward on the plate if ports on the side are blocked. I checked, and yup, by moving the plate, I can have *BOTH* the HDMI/USB and the Mic/headphone ports of my K-3 III unblocked. Sorry, my bad.
So... The 3 Legged Thing plate for the K-3 III fits without blocking either the battery access or any side ports.
