There is not as much of a scale difference between the old metals and the cadians.
I've got some even older (pre-attilan) RR (with slouch hats) range that have had torso swaps with cadians and they worked - and they are much the same size as the attilans.
I loved the Slouch hat look! i wondered about the difference, but the Attilans kinda fell in my lap, as it were. around $35 for the lot.
