Is this module replacing the content Author's name and avatar with OG's name and avatar?

Issue Summary

I'm looking for a solution for the following scenario: Mary Smith is a user who is maintaining the official page for the group called "Barack Obama". Because the system knows that she is an admin of at least one group, when she authors a new content, a module would give her an option:
"submit as:
--Mary Smith
--Barack Obama

The closest example would be the way that Facebook Pages are behaving. So if content is posted under the name of "Barack Obama" then in subscriber's news-stream we see that content posted by "Barack Obama" (OG name) with Barack Obama's avatar (OG image or imagefield)

I'm wondering if this is the kind of module that provides such functionality?
