Anyhoo, I think we agree on the fundamentals!
Indeed we do.
In FAA-dom, coverting the MDA to DA has to be on the chart, and is limited to commercial operators that get an FAA blessing.
Part 91 operators cannot obtain this approval, but there is nothing stopping them descending to MDA then trucking on level to the MAP. In a Cessna 182 at KLAX, that would probably work.
