Andúril light with true rgb? (lemmy.zip)

Is there an andúril light with actual rgb aux lights instead of the resistor ones or the single colour ones? If no, is it even possible with the microchip they use? I know its a pretty limited chip.

Unfortunately Neopixels consume too much power, about 1mA quiescent current each, also min Vin is 3.75V according to the datasheet.

The other day I found this small RGB controller, 200uA quiescent current (LEDs off), 300uA LEDs ON, which is much better especially with only one controller for all the aux LEDs.
