the guitar is tuned the way it is to maximize it's potential with open strings. If you wanted perfect tuning, you could simply move the second string up to a C and the first string up to an F. The guitar would then be tuned in perfect fourths, all the up the string set. You would have a much more difficult time playing chords with open string however, and you would lose the doubled E strings.
I would go with the G key harmonica, but the band would play in its minor relative key: E minor. It really unburdens the guitarists, for the blues progression would be Em / Am / Bm (or B7) and the Blues scale (Em pentatonic with the blue note added) is pretty much a guitarist standard.
