it should be quite doable to create the profile yourself. i would start with a generic IRGBW led (8bit) from the library. go to the fixture editor and have a look at the DMX column. there you can enter for the Intens,R,G,B,W parameters addresses 4,5,6,7,8. then insert parameters for addresses 1, 2 and 3.. if you will not use them anyway, you can just choose any parameter name and don't do anything else. if you want to use them you should fill out the ranges.
It does not sound like it will be possible to get this profile made so soon. If you can give ETC Technical Support at call [800-688-4116] we would be happy to assist you with creating your own profile. Use notification 300757482 so that my co-workers and I may reference these notes.
