Shouldn't really be a problem - I've had reasonable syntax highlighting of markdown files with support for inline code-blocks in different languages for a while in (neo)vim. Mixing languages/dsls in a single file shouldn't be a problem. Should also work for things like in-line sql fragments for orms etc?
