Custom LED drivers

I am using Adafruit LTC5947 to run my LEDs. As I understand currently there is no way for a user to add more hardware to the list provided in Arduino configuration tool. So my current ugly workaround is to modify NeoPixel library by removing original code and replacing it with calls to LTC5947 driver.

I guess I can always use CustomProtocol plugin, but I can't use LED editor tool with it, so I have to modify firmware every time I want to modify LED behavior.

So my request is - add a property that contains current LED colors (preferably base64 or hex-encoded because they are fixed length) so users could just send an array of RGB values via serial port.
