LOL.. I installed Thule Aero Bars on my wagon since the OEM bars are no longer available. I can install any basket that is compatible with the bars.
The ONLY issue you may have with it is that the rear of the wagon is lower than the front. The OEM bars have the rear bar longer than the front. If you install this basket using a Thule or other aftermarket rack it will look weird unless you can raise the rear bar. I raised the rear bar on mine by about an inch and it appears to be pretty balanced. But because of how the feet were on my towers I ended up making new pieces to mount the towers to. Mounting the towers in the front I was having issues getting the Thule stuff to fit because there are notches in the rail to allow the bars to be installed and the towers I am using wouldn't hold all the way forward because of those notches.. Now with a different base it holds fine and actually is stronger than the Thule mount. Did similar with the rear with a spacer that I had to modify to get to work. (The tower kit I got was for a specific SUV and came with spacers to mount to that SUV's root. The CTS rail slots are narrower so I trimmed off the rail guides that it had and it works great.)
If you don't mind the basket higher in the front then the back then you should be able to use Thule or Yakima bars and go with the basket of your choice.
