Can't see how much seatpost you are showing. If it isn't much, this suggestion may not be practicable, but if you need the bars as high as that, I'd say you could do with a bigger frame. A taller headtube would leave less steerer/quill stem exposed, which I'd regard as preferable, and maybe allow you to stretch out a little more without neck issues.

I wouldn't be worried about KOPS if I were you. It's a starting point rather than a rule. I know plenty of riders who prefer to sit as far behind the bottom bracket as possible so they are pushing through the top of the stroke. So if you wanted to try moving the saddle back a little, and down a little to compensate, to see how it felt, I wouldn't discourage you just on the basis of the KOPs idea.
