Interceptor's KG isn't important at all. It's the lightest mythical torso..and leave it as 309. If it was changed to 310/311/312 OR if your asking it to change from 309 to 312. ---> it really will affect everyone's Interceptor build. It's doesn't matter how terrible the torso, the KG should never change.
Brutality from 341kg to 340? It's a nice idea... but it depends on others' opinions.
It's never a good idea to have a Torso (any type) -- KG to be added +1 or +2 or +3.
Also the stats idea.... Sure..I guess
