These rules are superceded by the rule that the most absurd pronunciation is the correct one.
The name Ramkwich is a preversion of the English word language, as you can see from the table. Another example is "pretty girl", which becomes something like "bloody killer" (no, I'm not a nizochymizd).
You can make up your own preversions, since nobody actually speaks Ramkwich anyway, and if they did it would help make things more confusing.
Known speakers of Ramkwich: Lee Shirey, Carl Pollard, Gary Napper, and Bill Jackson.
