taking a feed from a light switch

So, an end-of-run switch is the last component in the wiring of a circuit, and in effect, the wire feeding the switch is coming from the light fixture and not the other way around. A second 2 wire is run from the first 3 way passing through the 4way switch box and on to the 2nd 3 way where the white is used to feed the neutral to the light and the black is capped off. The light comes on and there is power so I do not think it is a radial. I am attempting to wire a light switch in the middle of the circuit.

In this light switch wiring diagram the power feed joins the circuit via the light fixture where a two wire cable (C2) runs from the light, to the first 3-way switch (SW1), and a 3 wire cable (C3) joins the two switches. In this diagram, a new switch and light are added to an already existing light switch. There is a 14/2 and 14/3 wire in the box. If you take your cable from the socket to a Switch Fused Spur it must be in 2.5mm cable. Some of it's stranded, most of it cloth sheeting, no ground, bubba add ons and the circuits just make no sense so it needs to go. You can also see that another live and neutral wire go to the next light switch. Given that the light works when taking power from socket directly it must be because of how I am wiring the light switch. From the Switched Fused Spur the fuse must be downsized to 10/5 amp not 13 and then feed your light. 1. Can I disconnect the hot (black) wire and add a pigtail and feed power to my new switch?
