It's not Hello Kitty, but if you want pink Star Wars there there's the fan-built R2-KT, the pink astromech droid ... Hasbro evidently even made a limited edition figure of it. The whole project was the result of a request by a very sick little girl.
Unfortunately she didn't. Reading the website more closely it says Katie Johnson (hence "R2-KT") had a brain tumor and died in 2005 while sleeping.
I just happened to stumble across the website when doing a Goolge image search last week. There was a news item in 2007 on here already about the Hasbro figure.
