You don't want to swap the parts. If this is, say, a switch, it will take as much effort as building a whole new chassis from scratch. Exaggerating. Still pretty bad.

Not exaggerating much on this set. That band switch is three layers deep with fragile wires and components connected all over it, in a tight corner full of other stuff. You'd need one of those minimally-invasive surgery robot gizmos to do the work without breaking something else.
