I'm not sure what you mean by 'works only for separated output'. 
Separation colour spaces are defined so that if the colorant is 
available on the device then the marking operations use it.

If the colorant is not available on the device, wether the device is 
composite or separating, then the PostScript interpreter uses the 
supplied tint transform to select an alternate (device) colour space, 
and transforms the value of the component in the Separation space into a 
set of values for the components of the alternate space. It then marks 
the output using those components.

So if the ink isn't available, then you get a reasonable approximation 
of the marks it would have made, using the alternate space.

By the way, your code there is unlikely to work, since it has a 
different array of names for SeparationColorNames and SeparartionOrder.
