Doing that probably wouldn't break the balance of the game.That said, I'm not sure it 'needs' any upgrade. I realize it's not as strong as the other hexagon units, but with Daqan I don't typically focus on getting the Hex unit, I more try to get my Knights out often since their card option is very strong. When I get towers, it's just a nice bonus.
With the expansion, I admit I will almost always get a Roc before a Siege Tower, but even then, I'm not sure you need to change anything. But again, I don't think upping their health would break the game at all.
