Oh well, it seems, whenever I reach the point of thinking I will not find the 
solution by myself, in fact the solution is right around the corner.

For the record, in case somebody encounters the same problem in the future:
Create the "extension"-part (e.g. D in the example below) as a usual part. 
Don't call setWidget () in this part's constructor, though, as the widget is 
likely already in possession. Then, before adding the part to the 
partmanager, call something like this:

part_to_extend->insertChildClient (extension_part);

(or referrring to the example in the quoted mail: "part_B->insertChildClient 
(part_D);")

That seems to be all there is to it.
