I don't usually think about Suggests as alternatives to Recommends, but
rather things less commonly useful, but still enabling additional
functionality.

markdown, libtext-markdown-perl and discount provide
/usr/bin/markdown. You could test how well those work ootb, 
and recommend them as alternatives if it seems ok.

There are also conflicts between several of those, which looks odd to
me, but I'll investigate that seperately.
