I can very much see the canon Harry doing this. There was no bitterness in him, although he was uncared for by the Dursleys, he would still not want anything bad to happen to them.
His parting gift to Petunia is very much in his style as well, something to help her in her future, but at the same time a 'slap in the face' to her. 'I will help you and remind you that I am a better person than you.'
Good story.
