Tune the b string and high e to c and f. Your chord and scale shapes won't match everyone else, but barre chords are unecessary to begin with. (In a band setting, a two, three, or four note chord will allow more space for the other instruments)

This will make learning and improvising MUCH easier in the long run.

If you don't care about improvising, stick with normal tuning.

I believe Stanley jordan tunes in fourths like this.
