Let me start that I am in NO way saying "This is THE OFFICIALLY CORRECT WAY to do this", but it is a cheap and simple solution to solve this problem. (Did I mention it was cheap?)

I finally got around to installing the passender oil cooler and lines I bought almost a year ago, only to find that the fans were in the way of the R1 oil cooler hard lines. With the fans removed they do fit however there is only about 1" of space for the stock fans which was not going to work.

Instead, I decided cut the hard line that passed from the driver to passenget side, flipped it along the horizontal and verical axis and welded them back in. The oil cooler hard line now passes below the lower radiator pipe allowing plenty of room to install the stock fans.
You may have to do some bending to the hard lines to get them to match up where you cut them, however be careful as the pipe is very thin walled (.040" thick) and can collapse very easily.
One down side is that the oil pipe is succeptable to road debris bouncing up and possibly denting the pipe. Mostlikely a foam pipe covering will help protect from any debris damaging the pipe.
