It would be pretty cool if when a char was pked a screen would appear / menu would be able to be opened to show that chars stats. Like if after it shows your name with the dates you were able to see your actions and such. In my eyes these would include Pks done by you, overall kills, deaths, time played on that char and just a random little title for your stats. By title I mean if someone had an absurdly negative k/d it would be like Hospitals number one patient or if alot of time played it would be no-life.
I could see there being issues with past events and stats being loaded since the amount of time and how old log wipes are handled. Overall could just be a cool little thing for people to brag and show off.
