DMX-512 over 433MHz WIRELESS cheap radio

I am building very small wireless DMX RGB fixtures...currently hacking it together with eBay parts:

DM-103 3-channel DMX decoder

Wireless DMX module

Since the DMX & RGB LED requirements are easily met with an Arduino (or similar), and Arduino Programmability could offer even more flexibility or more channels, perhaps such a project could be accomplished with info here?

Very nicely, the eBay Wireless DMX Module also transmits to my commercial wireless DMX fixtures, so I can easily put all wireless stuff on one transmitter. Can the Wireless DMX outlined here be made to receive and decode from these eBay transceivers?
