Anyone make a 6 string bass E-E?

Lots of companies have made baritone guitars. Fender.

 

Danelectro Long Horn
Fender VI
Elrick Baritone
Jerry Jones...

Tons of them out there, but I would just get a 34 or 35 inch Six string bass and buy the gauge of string that would allow you to do that on a larger scale. A proper set up is needed though. The notes will come out clean with the additional length, oppose to bari's that tend to sound brittle or muddy... IMO

 

Fender did a japanese reissue of their 6 string bass a few years ago, with a 30" scale and 6 strings tuned E-E. Other brands have done the same thing, mostly 30" scales. Danelectro did one (discontinued now but probably still about), musicman do the silhouette, OLP do a budget version of it the MM5, Burns have just anounced that they are doing a baritone/ 6 string bass the barracuda. These are the main ones I am aware of. If you are looking for a longer scale length with that tuning I am not aware of any production models that fit the bill, thats not to say there aren't any, just that I have not seen them.
Hope this is some help.

 

If you want higher notes, why not go E - A - D - G - C - F, keeping the consistent tuning in fourths across the strings?

If you simply want something you can play like a guitar but get a lower sound, an octave pedal and a guitar might be better...

Just get a standard 6-string bass and a custom string set.

Edit: I think John Turner tunes his 7-strings B-E-A-D-G-B-E (like a 7-string guitar but one octave lower).
