That's quite a nice/interesting spin on the Kubicki tuning model.
This may sound a little weird/crazy. but go with me as this photo got me thinking - perhaps a little too much - and it's causing my brain to TILT a bit. There's clearly space on that neck to accommodate the extra fret and zero fret to allow the user to drop to a low D on the E string, so why not just take the frets over the whole fingerboard and tune down a full tone to DGCF? (I liked the theory behind Kubicki X-Factor, but always felt it would have been more interesting if the A string had had a double fret extension as well.)
I do understand the concept of tuning down on a regular 34" scale bass, unaware of the scale on this bass I suppose it's feasible a DGCF extension may take the scale length to around 38-40".

That's what Chris_b was asking earlier.
On Shuker no1 there is a bendwell under the other 3 strings, so no room there.
For the new build, it's again medium scale (32") having the extra frets across all strings would compromise that. And I'm not sure I could get my head around playing a detuned bass in bands playing in regular tunings, although Anthony Jackson seems to have managed before he went on to 6ers.
