I certainly understand your reasoning for replacing the AMST threaded parts with metric. That is the first thing that I do except the opposite way. I replace all of the metric threaded parts with AMST (American Standard) parts. It just makes it easier when you olny have to stock those parts that are most common to you.
We call this "Teaching the airplane American".

Most of the time I replace approx. 1/2 of the hardware that comes with any ARF.
After being in this hobby for approx. 35 yrs I have developed my particular likes and dislikes. And I am always willing to use a better stronger safer method.
