Hello. I'm insane, and have an urge to play as Squats. Sadly, they're dead. I want rules that could proxy them properly. What army should I use? I'm currently tossed up between having them "count-as" Space-marines (attack-bikes and landraiders), or having them "count as" Orks. I'm leaning towards the second option so far, with Squat Gyrocopters, attack bikes, and Exo-armor providing much ranged destruction. That and their higher toughness relative to strength, and their low initiative, fit the Dwarf profile more than the Marines do.
What would you advise ruleswise to properly represent these beardy gits?
