This is great. My main concerns are:

• maintaining text / image layouts.
• separating the tags - I would want to use different tags on my blog, and on the Steem version of my blog
• Consider adding a Steem footer, that would post like a "signature" only on Steem, but not on Wordpress. You see these sorts of footers sometimes with people saying for example, "Vote for me as Steem Witness." They will put that at the bottom of all their Steem posts. That is good for a Steem post, but makes no sense for a Wordpress post.
