Do any alternate guitar tunings make it easier to play close voiced (piano like) chords?

If I'm trying to emulate piano-like chords on my guitar, i find it hard to do in standard tuning because the strings are seperated in fourths and my hands can't stretch far enough to pull off certain chords where say I want 3 or 4 notes in the same octave instead of a big spread-out guitar like chord that takes up a couple octaves.
