Because I am a stereotypical internet user, I am too lazy to read all of the pages of this thread to see whether or not this has been suggested, but how about having the levels of CCLP2 and CCLP3 as ranks beyond level 149? I personally like the CC1 level names as rank titles more than I like the other proposals, but an extension wouldn't hurt.
And if this idea HAS been proposed before, then, um, I second it! A lot! I very second it!
