[@agentmanatee], Hmmm. I am actually bored, too. I was thinking of giving her a bit of a wisp. Her R's won't be as audible at the end of sentences, and when at they are at the beginning they may sound more like W's. So, it may sound a bit like what we know as an English accent, but not quite due to the W sound.

Example One: "Wun fastuh!" would translate to, "Run faster!" Spoken quickly, I'd say it's not as noticeable. 

Example Two: "Aight, evy'one, let's get our shit togethuh," would translate to, "Alright, everyone, let's get our shit together."

Does that sound alright? Or is that too confusing?
