Glad you liked it. There is indeed no reason not to use similar rules for other naval wargames.
The problem I tried to solve is that naval engagements often are interesting due to specific circumstances and timing which offset evident numerical (dis)advantages. Opposing fleets often are very assymetrical, but battles still come to unexpected results because of concentrations of force, maneuvering et cetera.
I myself was contemplating the Java Sea as a second subject for such rules.
