Tuning in THIRDs

Now that 6-string basses are easy to find, I wonder: why not tune in major thirds, e.g. 4 half-steps rather than 5 between strings? A 6-string tuned in thirds would have the SAME range as a normal 5-string, i.e.
B.D#.G.B.D#.G = BEADG.

The attractions would be:
MUCH more nimbleness;
arpeggios lie more naturally;
Chromatic scales require no shifts (so neither does any other scale);
Easier to play chords if you want;
easier for duffers to play without looking; and
might be an easier shift to fretless.

Each hand position gives you 24 notes, so you get two octaves with just one finger extension.

If I've counted right, here are some fingerings:

A major scale can be fingered e.g. 35.34.24.23, or (for two octaves, using six strings) 24.235.35.24.235.35.5*.
(Using pianists' numbers for the fingers, a . to show string changes, and a * to show finger extension.)
A major chord or arpeggio can be e.g. 3.3.2.3.
Fifths can be 3..2 etc.
Octaves can be 3...3 or ..5 or 5....2.
10ths can be 3....3 or 2*...5*.
I-IV-V can be 3.4.2.

A five string gives you a bit more than a normal 4-string range, e.g. Eb G B Eb G, and gives you 20 notes in each position. This might be more practical for people who like 19mm spacing and don't have super long fingers.

A four string gives you 3 half steps less than normal range, e.g. E.G#.C.E, but the extra nimbleness might make this attractive. For soloing up the neck you might want to do some position shifts like pianists do, where you use one note to gauge a shifted position for the next one.

This tuning isn't nearly as attractive if you're not doing one finger per fret, so I'm guessing it wasn't ever used for double bass - does anyone know? It may have been tried for guitar or lute long ago, but that's a different world.

I'd love to hear frank comments, especially from people who are better players and/or better musicians than me. I'll have to string one of my beaters this way, and see how it feels.

I love ideas like this and find them terribly interesting, but they all have the same problem... you are now tethered to THAT bass. If you ever have to use another one for some reason you're completely thrown off your game. Even though this sounds way better (logically) than "standard" tuning you will forever be living in a world of foreign tunings.

Triple sharps! Rugged!!
Too rugged for me! In all honesty though, I don't really see the utility in tuning to thirds. I see much more in tuning to 5ths since it gives you further capabilities in less physical distance. I can definitely see how comfort is a major point for which to condense the intervals, but I absolutely see more utility in being able to cover a two octave gap with a reachable distance in that 5-12 fret area.
 
I guess the basic choice is whether each position should include a solid block of notes; if not, then there will always be unpredictable needs for shifts and extensions; and (what is almost worse) the choice of fingering will be important. M3 tuning means that fingering doesn't really matter.

I practice my shifts too, but that doesn't mean that shifting is a good thing; rather it's a necessary evil, which makes it harder to carry a good legato.
 
I've experimented with thirds on 7 string guitar. It's a fun alternative tuning. Doesn't even require restringing if you leave the center string where it would be in standard. In my case that's D F# A# D F# A# D.

To me it makes more sense on guitar, since it makes chord shapes moveable across the neck. Bass is already symmetrically tuned, so that advantage is lost.
 
after an infinity on the piano (with nimble wrists prone to (re-)developing carpal tunnel syndrome) I've started playing the bass at 46. went at it with a sense of engineering and ergonomics in mind: bought a five string (can go low with my right hand closer to my body), tuned it down half a note to get less tension, less pressing force needed, and raised the strings to compensate.

Since I know music but not the bass I figured I might aswell learn it at an ideal configuration. first I used a minor / major / minor / major / minor thirds tuning, which puts all the notes of an octave within four frets, and produces nice chords. But it is a little complicated, as scale fingerings change from one string to the next. So I went for the all major thirds: Bb D F# Bb D.

Had to put together a custom set of strings to get equal tension, and needed to slightly alter the bridge to be able to get the intonation right.

Now i am truly enjoying the instrument: there is a great logic to the fretboard, it's intuitively playable, and I'll report back once I've gotten around to going beyond improvisation and to learning some of the literature.
