So, likeness rights is one thing...but for who ever they have, it's actually not that difficult to get most of the squad without making too many new pieces. Everyone obviously needs a new head, but the basic male body they have for Hicks and Hudson can be used for Frost, Wierzbowski, Crowe, and Apone. Ski could use the same arms as Hudson, the other other three would need a new set of arms with long sleeves. Drake could use the same legs, and the arms from Hicks, and Vasquez and Dietrich could probably use the same legs. Dietrich and Vasquez would both need new torsos and arms, and Drake would need a new torso as well. (assuming the armor is molded onto the bodies and not just glued on, I didn't even really look)
Gorman and Spunkmeyer might be able to use the same bodies as well.
