Just use them squat minis with IG rules, problem solved.

They deserve noth more than Carapace anyway, since we all know that in reality they make squat that is useful.

Tau rocks, so stop being so nostalgic and give the manga kids the nod. They deserve something too. Also, nothing say "Screw hand to hand" as a pulse rifle to the face.
And better, if you really like those minis, just play Mantics own game and do not sully the glory of the 40K universe with space dwarves meant to be taken seriously.
