Answer 1

May be this (untested) snippet helps a bit - it uses the the .NET api for ImageMagick.

MagickReadSettings settings = new MagickReadSettings();
settings.ColorSpace = ColorSpace.CMYK;
using (MagickImage image = new MagickImage())
{
  image.AddProfile(ColorProfile.CMYK);
  image.Read("image_rgb.tiff", settings);
  image.Write("image_cmyk.tiff");
}

If you can use the commandline this will also do the job:

convert image_rgb.tiff -profile "RGB.icc" -profile "CMYK.icc" image_cmyk.tiff
