ECI profiles are as much and as less for europe only as Adobe profiles are 
for north america only. What would say south america or australia ;-)

Tino,
you dont need to convert to an intermediate colourspace for separating to 
Cmyk. Just convert from the image colour space to the destination colour 
space and you should be fine.

Even though for editing, the above profiles are good choices, including 
LStar-RGB.

The photometric intent is implementation dependent and thus not a 
relyable choice for corporate colours (logos). Colour shifts are possible.
Hence the often recommendation to relative colorimetric.
For photos the photographic intent gives often better results.
 
Viel Spa?.
