I can't get on with 5-strings either. I converted a 4-string to BEAD; filed the nut out, set it up again - lovely. And a possibly controversial opinion: if you miss your G-string then you shouldn't be spending so much time on the dusty side lol!
I believe Spector offer a BEAD bass with a 35" scale.
Have you considered an octave pedal? My MXR's awesome!
