Kusanagi is somewhere between levels 14 & 20 (to the point that arguably Daisuke Aramaki is her personal lieutenant): trying to map a 1st level noob against her -- which is exactly what we're dealing with here -- is an exercise in futility. Similarly, everyone you're offering up has been doing their thing for a while.
And again, you're both still overlooking that this is a feat, taken in addition to whatever origin the character picks, not to mention their class choices, subsequent feats, level-based adjustments as well as Reputation benefits and any Treasures they might have (because as it stands, that's the easiest way to handle the chrome). It's very easy to start without a negative Charisma mod, while smart origin choice still lets you start with a positive one.
Basically you guys are looking at one feat and assuming it's the be all and end all, when it's just one part of a rather larger picture.
