This is what a CMOS 555 (TLC555) manages, translating from 5V to 12V. The input (blue) is from an Arduino UNO, the output (yellow) is the unloaded output from the 555 with a 12V supply.
For some reason, I imagined that the CMOS part might be faster than your bipolar part, but it isn't.

You're welcome. It doesn't help you with your WS2812, but it might be useful to others who simply want a slower driver. One thing to watch with this particular CMOS part is that the output isn't very balanced, 10mA high/100mA low.
Thanks for the EDN link. I didn't know about the shoot-through, though, as you say, it does maybe explain some of the warnings about wiring the RESET high if it's not driven and considering decoupling the CONT input. Wonder if my CMOS part is the same? One way to find out, I suppose...
