Composite Weighting for Area Interpolation

[iki77]

I have a source df and a target df that already have population variables, and want to interpolate GRP variables.
Normally area interpolation only considers the area of both source df and target df.
Is it possible to add additional variables, such as population, for the weighting?

Area Weighting: Area of intersected feature/Total area of the source feature
Composite Weighting: (Area of intersected feature + Pop of intersected feature)/(Total area of source feature + Total pop of source feature)

i think this is a duplicate of #137?

The difference is that in #137 it only changes the weighting of intensive variables from area to other variables.
What I propose is to add other variables to weighting in addition to the area for both extensive and intensive variables.

Here is an illustration for GDP interpolation:
