I mean separate patches and separate modules.

If it´s not normal JPEG 2000, then you can´t hijack the existing JPEG 2000 
codec identifier for the purpose. That would conflict with existing uses.

Just output the I422, YUYV or UYVY, whichever is simplest, without conversion. 
Core will automatically insert conversion filters if necessary.
