I think that is too small-scale. POW is a fair bit bigger than that - the dogtooth sections are obvious from a few feet away rather than blending into a varied gray. Basically the black and white pieces that make up the pattern are bigger, as if the pattern had been put under a magnifying glass.
Here's a good example from Sir Paul, though the colors may not be authentic:
And yes, a POW check jacket is a good choice for an odd jacket, but it's better done with a larger scale and a softer fabric as opposed to the fine scale hard worsted you often see in suits.
