Don't worry about being under points; focus on making armies that you are comfortable playing. Hitting point totals exactly is pretty overrrated. Just make sure every piece you put in the army has a clear purpose for you, even if that purpose is just "sit in the back and use if everything else dies". If you are really worried about losing on time because you're playing under points, then add Pelloth or something. (Your dad could just add another human champion and roll with that - personally I'd drop Denrick and add Thorgrim, Hawthorne, and Eldgrim.)

Your army looks a little strong for the Gencon main event metagame, but if you feel like you can't compete without something like that, knock yourself out. An army along the same lines that had popped into my head was Deathreavers x4 + Braxas + Jotun.
