Hello all,
Yeah, I already knew that squats were space dwarves, howevre, just like you, I don't know what the models look like.
If the armour isn't too heavy/apparent then I think it's no problem at all modelswise. Even if they do have heavy armour you can always take some fluff to back it up (btw, you might want to use them as guard squads instead, because the basic guardsmen does have armour).
Just some ideas to toss around.
