I've got an easier solution...get a Bass VI for another twelve notes on the B and C strings! You can get all the way to the A on the 14th fret of the G string at the 5th fret of the high E.
Man, go to jail for playing like Jaco, go to jail for only playing on the first five frets, get the electric chair for playing chords, I just can't win. I'm going to take up the kazoo.

40 minutes! I've been at it for 50 years and still can't find that darn Cb and E#.
FOOTNOTE:
The Fender Bass V of the 1960s was designed with a high C string (tuned EADGC). The fifth fret of the C would get you to the F that's on the 10th fret of the G string. Since you had that C string, Fender threw away the upper 5 frets...it's only got 15 frets but you can still hit that high Eb except now it's on the highest fret of the C string
