This is a very crude idea and I am just a beginner about Wordpress, but I want to share my idea(or wish) with the community.
As you may know, Steem is a database that enables reward-based contents creation system. So its position is similar to MySQL or MongoDB (while Steemit can be compared to Reddit or Facebook).
Given this fact, my idea is simple; Use Steem as a database of Wordpress with SLAMP(Steem, Linux, Apache, MySQL, and PHP). Here's a rough diagram.
Database converter from Steem blockchain to MySQL
SteemSQL already made a good start. However, SteemSQL still have very different structure from Wordpress's MySQL(See Here and Here). We need more efforts to synchronize them.
Steem login module + editor
SteemJS or SteemConnect already made it too! But we need to make it as a Wordpress plugin with editing features.
Remote public node
For average Wordpress operators who don't want to run a $100-month server, we can provide public node with Steemd websocket endpoint and remote MySQL database. It can be opensourced, and either free or charged service.
Full SLAMP and Light SLAMP
Most of all, users easily can install a full package of SLAMP on their VPS. This should come with user-friendly documentations. And we also need to provide a easily install-able light SLAMP, in which Steemd and MySQL is outsourced.
The advantage of this maybe Steem can expand into Wordpress ecosystem. However, custom database tables created by some plugins can be problematic and should be addressed.
I want to add a simple story to stimulate your imagination.
Bob wants to have a blog. He found that Steem-based Wordpress blog can give him real rewards so he want to install it.
He opens $5/month VPS on Amazon, and downloads a light version package and install without any hassle(or can create VPS via Steem-Wordpress image). He also adds some cool plugins that support SLAMP. Then he opens a browser, goes to his blog site, and writes a post via provided editor. The post is recorded on Steem blockchain through remote Steemd server.
Annie is surfing the web, and visits Bob's blog. She thinks the post is good and notices there is a upvote button. She logs in via Steem Login(assuming she already has Steem account), upvotes Bob's blog. She also leaves a comment to Bob. It should be mentioned that Annie is also enjoying Steemit, Busy, and other many sites that are based on Steem blockchain database.
