Multiple display setup mac, ignore separation between displays

I am currently setting up my workstation, and I want to use the set up pictured here:

As you can see, the display on the top is turned sideways, and that is the way I want it.

The question is this: how can I make the cursor jump between the left and right monitors and the top monitor smoothly (rather, at all), as if the top display was just as wide as the bottom center display? Right now, the cursor can't cross directly over the separation between the top and the side displays.

The desired behavior is that which would result if the top display was just as wide as the bottom, so there wouldn't be any disconnect between the displays. However, I want to keep the top display oriented at its current orientation.

I am using a retina macbook pro, early 2013, on OS X 10.10.1.

That's not really what you wanted, but have you tried this arrangement?
