imagemagick can only be removed when nothing depends on it. imagemagick-6.q16 has been marked as replacing imagemagick, so most packages which depend on imagemagick will automatically use imagemagick-6.q16. However some packages, including cups-filters, depend on particular versions of imagemagick and the automatic replacement doesn't appear to work in this case. You will only be able to remove imagemagick when cups-filters' dependencies are updated or imagemagick-6.q16 finds a better way of declaring that it provides imagemagick. The :386 packages are irrelevant and only need installing in very specific circumstances. Roger
