How can it work? The MD degree has a long history and worldwide recognition. Why in the world would the entire US (perhaps worldwide?) MD community want to change their name, spend money re-stitching coats, buying new cards, making press releases, etc. because a subset of osteopaths may think that looks better?
Also, the majority of DO don't want to or care to change their degree because they either a) have some pride in it, and b) they don't find any necessary reason to do so. I certainly wouldn't want a degree change unless it's to differentiate from non-medically trained osteopaths. If I wanted an allopathic degree that badly, I could just head to the caribbean or another foreign country. I'll be grateful for the opportunity to learn medicine in the US under the osteopathic tradition.
