If performance is your goal, you'd be well served to focus on PWO nutrition and adhere to it. If looking good nekkid and health, longevity etc. is your goal, PWO nutrition helps but isn't entirely necessary.
Have you checked out Lean Gains? Like everyone else said, do what makes you feel the best while still allowing results.
What is your workout approach like? As in, what kind of activity do you do.
Why not just extend your eating window so that you can still eat PWO, and start eating later in the day.
Keep it intermittent to allow for feedings on WO days, and not so much on rest days.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
