As of now, MXM is the only open source dash (besides nexgen, i think)
But even if the other teams could be convinced to release their sources, I don't think they will like working together on one dash.
The main reason is that each team has their own idea of what a dash should be like, and that's what they work towards. For example, some teams prefer functionality over appearance, and some otherwise. Therefore, it's better for each team to achieve what they want, and the user can choose what is right for them.
Another problem would be to decide which dash to work on, if the teams merge. No one would want to abandon their dash. And making a new dash from scratch would be too much work, and will take a long time.
In short, I don't see it happening
My slightly more than 2 cents
Edit: and who are you referring to by 'US' in the title?
