Make blocks availaible for Winter.Blog plugin

[damsfx]

I've tried replacing the blog editor with blocks.
This try is currently available as a plugin, not sure if it would be of interest to users of the Winter.Blocks plugin.

The plugin is available here : Blocks for Blog plugin

At this time :

• Replace post editor by blocks if enable via extended Blog settings.
• Add a special block to use already uploaded featured_images attachments in content with a dedicated dropdown
  
• Save the blocks definition in post metadata and convert blocks render to HTML and markdown for backward compatibility if this plugin is disable (or post editor replacement setting is disable)

That's say, I was wondering if it was possible to create a block that could use content_images attachments by offering a drop zone for downloading, replaced by the image afterwards (as in the split base editor's preview mode) ?
