That would work nicely, now the question is, do you want Heatran more offensive or defensive, and if you have a Heatran, you need something that can resist the ever so common ground type attack.
Personally I would recommend Scarf Landorus-T. One of the best U-turners in the game, Intimidate+Flying type counters many Fighting-type threats, and is immune to Ground thus befitting your needs...
