I'm no morat player but imho the game niche for not at army should be "staying power". Esthetics: Morat miniatures are extremely beefy and armoured. Even though they are ARM 2 or 3. Rules: Morat favour heavily multiwound models and is definitely well characterized. Modifications: simply give +2 arm to every Morat at the expense of +1 PH or +1 WIP. Tldr: make Morats the "Chief say to take that hill, lets advance under fire and take that hill" basically the Dwarfs of Infinity
