Interesting blog linked to below. We are starting to see models like that discussed with 'dispersed' firms like Excello Law, Keystone Law etc but obviously not on the scale envisaged.

Clients engage their “trusted adviser” who has highly-trained project managers as well as other para-professional specialists available to lend required expertise on a transparent, integrated, highly cost-efficient basis. Translation: the “trusted adviser” comes without all the baggage endemic to the BigLaw model (and that includes other cost escalators including opulent real estate and bloated staffing).
