Welcome to Geekhack!
Sounds like you need to convert a few of your friends

Be aware that most keycap sets are not backlight friendly - i.e. they will not let the backlights shine through the legends on the keycaps. If they keycaps are sufficiently thick you can get some nice underglow!
There are a few aftermarket sets available that are backlight friendly, but they tend to be just plain black or white, and not much different from what you have now.
