Weapon systems, as with any piece of tech, can be theoretically swapped even if they are built in. However, due to the unique quality of the Framewerks created for the Project, this would be an emergency measure, as removing a limb from them and replacing it with another or even changing the handheld weapon it was originally constructed to use results in a loss of synchronization for the Frame, with case-sensitive exceptions like with Roxy.

I don't quite agree with that, but there is certainly a couple of years of difference in maturing rate between boys and girls.
