I'm currently working on forecasting/analytics applications using extjs 4 as the front end.

An idea I've had is to be able to edit the charts by hand to allow the user 'what if' analysis.
Basically what I mean is a user can grab a point on a graph and move it up/down.

The changes would then be reflected across the application.

I don't suppose if anybody knows how feasible this idea is?

Seems feasible. A nice challenge. But, feasible.
The chart's layout will be driven by its underlying data so if you allow the user to drag a point you'll have to translate that new location to a point in the dataset within the chart in order for the rest of the chart to redraw.

Best of luck!
