Anything apart from the two mainstream default harmonicas (Solo-tuned fully-valved chromatic, and un-valved Richter 10-hole diatonic). Alternate tunings, different construction, new functionality, interesting old designs, wishful-thinking... whatever!
BASIC CONCEPT:
Recently I have felt the need for five particular chords in a lot of blues/pop/rock tunes. From low voicing to high, they are: bVII (in this example, Fmaj), I (Gmaj), bIII (Bbmaj), IV (Cmaj) and V (Dmaj). I also managed to give four of these chords (the exception being the bIII) the option of being played with or without a b7th.
WHEN/HOW: January of 2018. I have not yet had one made.

The 5 blow and is shared between two chords: as a root for one chord and as perfect fifth for the other chord. Therefore, it can be tuned to ET and will sound good for both chords.
The same is true of the 5 draw.
The 7 blow is shared between two chords. As a major third it should be flattened, but as a root it should not. In this case, I would defer to the latter and tune the note to ET.
None of the major third notes are shared; they can be tuned to ET -14 cents.
None of the septimal minor seventh notes are shared; they can be tuned to ET - 31 cents.
