Interesting idea.
Took a photo tonight.

With the adapter, I can't get a good grip on the oil filter to spin it off by hand. Not enough room for fingers between PS - FILTER - ENGINE MOUNT. And, it has to be done from underneath, in and around the frame braces, tie rods, panhard etc.
By comparison, the standard location, the filter is easily gripped by hand, by reaching in from over the fender. There's a few houses and wires in the way, but they push out of the way.
Small style filter is even easier.
