I'm hoping to make some 4-pin RGB LEDs (R, G, B, GND) easily hot pluggable, so I'm wondering if 4-pin S-video connectors could be used.
Now, 2 of the pins on a S-video connector are GND, so would it be a good idea to abuse it and connect it to one of the colours? I'm just trying to cause minimal damage if it is plugged to another device with a S video female, and vice versa.
Here's the LED
Soldering will do the job but normally these are intended to be assembled using a crimping tool that fastens the wire on the pin.
Here is a video tutorial
The Raspberry Pi's seriall port pins on the GPIO header are 3.3 volt logic levels direct from the processor. The processor will likely be damaged if you connect real RS-232 signals to those pins. You will need an RS-232 interface chip (MAX3232 or similar) to invert the RS232 signals, and convert them to 3.3 volt logic levels.
Then you should use a multimeter to determine which wires in the cable connect to which pins on the RS-232 connector.

S-Video isn't very common anymore, at least in the 'states. But still, it could happen. Is this for cable-mount, panel-mount, circuit-board mount? How about something like this?

Low-profile, easy, fast. It's up to you to make sure it's connected the right way. There are "keyed" variants of these also which make them only connect one-way.
