Delete Posts After Sending to Subsite?

I want to do the following with my multisite setup: Send a post from the main site to a sub site, automatically deleting the original post.

I have the Distributor plugin, which copies the first post to the sub site, marking the copy as a draft. But the original post remains. I want the post on the sub site to be the post that’s indexed. I could manually change the canonical to point to the sub site post, but with thousands of posts that would be a huge chore.

So, is there a plugin that would automatically do what I need?
