Final note: I must admit, that my conclusion is BS (also the reason why
the problem is not urgent any more).
You can't combine RGB and GRAY color profiles as output intents (IO) in
PDF/X-4. But the usage of different colorspaces in the document (like
RGB+GRAY) and the IO (like CMYK) is valid. So no need for any color
conversion. My error in reasoning...
