Vasoline an a heat gun works great for waterproofing. It also makes the leather swell a bit to seal up cracks. I use it on my boots twice a year.
Obviously the water proofing is one of the big issues I have. Where your system would fail, as have all my previous attempts, is that once the leather cracks, or gets torn, you have to re-apply. I'm hoping that the bed liner will stand up to kicking pumps, concrete walls, steel grating, metal stairs ect, while maintain it's water proof-ness and maintaining it's chemical resistance.
