A dedicated change management team anyone?

We've sort of had discussions around this before, but in an ideal world wouldn't it be great if the following occurred.....
1. On a Monday, at the start of a job, we had the most brilliant Works Information and Accepted Programme (I saw you roll your eyes then..!). We were in a position to therefore manage the job for once and not just administer it.
2. During the day there were a couple of early warnings notified, a bit of a Contractor delay discovered and 2 compensation events popped up.
3. On Tuesday the [change management team] (basically add whatever name you want here) worked through the 5 things that arose on the Monday such that first thing Wednesday we had made a few changes to the Works Information, the Completion Date happened to stay the same, the Prices (let's assume it's an ECC Option C target contract) moved up a bit, we had a new Accepted Programme and the forecast Defined Cost slightly changed.
4. Repeat 2&3 for the next 6 months/year/whatever the duration of the job. The point being, we had some dedicated resource to work through the entire effects of the day before and conclude them all that day ready to pick up today's stuff tomorrow. Make sense?!

So,
a. do people do this (or have done, I'm not just talking about CEs)?
b. is this realistic?
c. do people want this?
d. what might this cost be and would this be cheaper than the way we do it now?

Answers on a postcard please.....

For dedicated resource I was thinking that Employer/Contractor pooled very capable people (planner, estimator, designer, QS, buyer and so on) and somehow split the costs. Possibly not even full time commitment, at least to start off. We're away from man marking here and we're into a real time process of dealing with risk and opportunity.

Insane end of the week head in a bucket of sand stuff, or something that would turn the industry on its head in terms of how we actually address risk and opportunity on a real time basis?
