In my opinion I don't think it will cause a problem in the context of a les paul cavity, but I thought I'd mention it.

In fact the best method is the 'star' method which the plate uses. ie, all grounds join at the same point, the pillar on the plate.

Back to the subject of grounding the strings, I read this on a website, which may be helpful:-

"On any good quality guitar, you will find a wire running from the bridge
to the earth side of the guitar's wiring. This is the string earth, and is
essential for cutting down string hum and noise, and you can add this item
to replace it altogether.

Wire together in parallel, a 220k ohm resistor (red, red, yellow and
silver or gold) and a .001 capacitor with a minimum voltage rating of 500
volts. Twist the wires and then solder them together on both ends.

Wire this unit inside the guitar between the bridge or tailpiece and the
earth side of the circuit, replacing the string earth wire.

In the event of the chassis going live, it will only send about 40 volts
through the strings, enough to give you a warning tingle without hurting
you. It will allow enough leakage for the string earth to operate
normally. "
