Default values of a node reference cck field from the values of the referenced node (outch!)

Hello, I try to make something a little complicated. I prefer to explain it with an example. I will try to explain better if you don't understand.

Three nodes type:
Node type A
Node type B
Node type C

Two cck node reference field:
field_lien_fiche
field_name

field_lien_food is a field from Node type B and makes reference to Node type A.

field_name is a field both in Node type A and Node type B and makes reference to Node type C.

I would like to set the default values of field_name of Node type B with the values of field_name of Node type A.

For exemple, when I set values of field_name in a Node type A: (multiple values)
Potato (Name of a Node type C)
Salad (Name of a Node type C)
Egg (Name of a Node type C)

I would like to have automatically:
Potato (Name of a Node type C)
Salad (Name of a Node type C)
Egg (Name of a Node type C)
in the Node type B (with reference field to the Node type A).

Is it possible?

Thanks

ps: I don't know what title I could use for this. Be free to change it :)
