- Setup a new Blogger account, make that account a blog administrator, and activate Mail-to-Blogger for that account. If you're daring, use your existing Blogger account.
- Setup a new Google+ Circle.
- Add a single user to your new Google+ Circle, using the email address of your Mail-to-Blogger account.
- Share something in Google+. Include the new Circle as a recipient, and select the "Also email ..." option to target the Mail-to-Blogger address.
- Done. Enjoy the convenience.

You may want to select "Save emails as draft posts" in the MTB setup, and plan to edit each post, before publishing it. It you publish directly from the Google+ stream, your posts may be a bit cluttered looking. Look at my test blog post, if you wish.
It's also possible that the footer in the Google+ post may contain something like
You received this message because xxxxxxxxx shared it with email@example.com "ssssssss" will be the secret portion of your MTB email address. Publishing the post, with the footer included, could expose the MTB secret word. This would produce a new Mail-to-Blogger security vulnerability.
