Krampus fork, bottle and cargo cage advice

On the Surly Krampus fork there are cage mounts on the back 45° and one mount on the side 90°. However, no mounting points on the front 45°. I want to run a bottle on the back 45° and a small cargo bag on the front 45°. How can I achieve this so it is sturdy and reliable for the long haul? Thanks in advance!
