Inadvisable? So are half the things Harry does in Harry Potter, including destroying Voldemorts Hocruxes, fighting the basilisk, going into the Dark Forest, and yes, time travelling to save Sirius Black. Let's face it: Harry would gladly put his life on the line to save the people he loves.
But I agree that he really shouldn't be in, and it is unlikely. The ending of Deathly Hallows was so happy that it would be a mistake to bring him Harry back. I want to see new characters.
