It is, just like the regular full sized MNT reform. You can reprogram the keyboard firmware (or even get a different PCB made as some people have done for the regular one). Part of the limitations on the layout is making it fit in a standard size while using off the shelf keycaps. The full sized reform only uses 1u and 1.5u key caps so the row spacing is off, but it eliminated having a bunch of odd sizes. Which also meant the space bar was split in two. Honestly for such a small device there's always going to be compromises in the keyboard. Either excessively small keys, or non-standard layouts. Just look at any of the UMPC offerings from the late 2000s, the Pocket CHIP, or even more modern ones like the GPD handhelds.
