I disabled the default toolbar with shortcodes and replaced it with my own with Kramdown versions. I hooked the Add Media button to output Kramdown instead of HTML as well. Also we're having our editors write Kramdown.
Lastly, when pulling all the data, I determine if the post is HTML or Kramdown and use the Kramdown library to parse the HTML.
Everything migrated from the old site was automatically converted to Kramdown this same way and had to have some minor cleanup work done on each post. Not a small task on our main WordPress site with 7000+ posts/pages.
The interesting part was that wp_autop() happens at render time, so to get Kramdown to parse the HTML correctly, you actually have to RegExp replace '\n\n' with '<br /><br />' first to preserve paragraphs.
