You could do that, and then just repaint the gold part silver.
Also worth mentioning, the blade that comes with all sabers is a translucent white.
For long events or events outside, you will run out of battery power at some point if in constant use, plus in daylight it doesn't look that spectacular. Hours of hearing the lightsaber sound is also annoying after so long.
I ordered a Vader's Vault "Day Blade" in Red, now I don't really turn the saber on as its always red. I do turn it on for photo ops, but normally i carry the saber in the off mode 99% of the time.
I am a Fan of Vaders Vault, not just because of their workmanship, but also because of their warranty.
Saber Forge has some really nice saber bodies, just their electronics is on the crap end of the spectrum. Getting a SF body, and then having someone else do the electronics is another option people do. Some people get lucky with their SF purchases, I am not one of those lucky people. I may just order a Day Blade for that saber, and then just not turn it on, as there is a problem where it turns off in mid use sometimes.
If I had to do it all over now I would get a Stunt Saber (no sound) and a day blade in the color I needed. Yes it's fun to play with, with the sound, but after 2 hours, the fun faded for me lol.
