I was looking at the HF website when I found this

Seeing this brought back memories of a picture of a desert race truck that had multiple long hydraulic cylinders built into the frame that could be used to quickly lift the truck for fast tire changes.

Now I was wondering if you could adapt something like this for our use. Perhaps weld some sort of pocket with a hole for a pin onto a couple locations on your frame. When you need to lift one corner of your rig, place the top of the jack into the correct pocket and pin it in place using the hole on the end of the jack's rod, then use your OBA to pressure up the jack. I figure the ram can't be much heavier than a Hi-Lift, and quite frankly probably alot safer.
