I downloaded the KnockoutDock script from the MacScripter site and decided I didn’t like the invisible Dock, just as I never liked hiding the Dock. I did like the placement and (pretty much) the size though. I aslo wanted Dock components to magnify for me.
While I am far from ready to create my own Apple Scripts, I could see and modify the script supplied. I had it leave the Dock visible and enlarged it from 16 to 18, and turned magnification back on.
Perhaps someone else will like these suggestions.
