I agree, unlike lynx's who have modular chassis, the arachnids chassis are different, which means that a spider chassis cannot be used to hold a scorpion beam wep, and a scorp chassis can not be as fast or as agile as the spider, and cannot repair or reprogram
and if this new arachnid is made, it would also have a specialty chassis (btw I agree with the claws, it needs a way to grapple) and would not have the same capabilitys as the other 2
