This is a little strange tbh. The majority of markdown parsers will allow inline html elements too.
If you're trying to do a large structured document, which will need block specific styling, try Pug. (Formerly Jade.) HAML & Slim also solve similar problems and have the benefit of a pretty significant userbase. (All support embedded Markdown)
