Seypat, I've seen a few bikes with a zigzag/harlequin patterned wrap, but never the type of pattern you're suggesting. It might work with thin cloth tape, but wrapping two layers separately like how you're suggesting, I think that might get pushed out of shape more easily, and might make the grip surface uneven and uncomfortable. There's striped bar tape out there- less ugly than a lot of that splash-patterned cork stuff. What color combo were you going to do? What bike is this going on?
