I've done the second and fourth suites in recitals, and both work fairly well on CC.
For the second suite, I transposed the original down a perfect fifth, putting the movements in a comfortable range. I did this in my undergraduate studies (junior recital, I think), and used the "rolling chord" technique Wade described earlier. Note that you don't ALWAYS have to sound the notes of the double, triple, or quadruple stops that the original has...it's perfectly ok to just sound the melody note sometimes, especially in the faster movements (Prelude, Allemande, Gigue). In the slower movements (Courante, Sarabande, and the Minuets to some degree), it's agreeable to "roll" the chords and try to get the lowest note to ring a bit.
I did the fourth suite on a graduate recital. This time, I transposed down a minor third, changing the basic key from Eb to C. I think this suite "fits" the tuba a bit better...it seems to concentrate more on horizontal melodic movement than vertical chords. I didn't use any "rolled" chords this time (there aren't as many as in the second, anyway), but rather used multiphonics for the Saranbande and second Bourree. The Gigue is fun on this one...you can work it up very fast and it makes a nice recital piece with some "wow" to it.
General ideas...obviously, breathing is a problem when playing a piece for a stringed instrument. Find the phrase points and use rubato to create breathing points before continuing to the next idea. This is most difficult in the Prelude movements...they can be quite a blow until you get some speed to them. Don't be afraid to find some workarounds and create your own "arrangement" of these...that's part of the fun!

You mean like this?
