I doubt that that's possible in the way you want, since ruby is not 
strictly typed, so this kind of type-casting won't work.
However, there could be ways using metadata- you'll have to wait for an 
expert to answer.

Simple way:
put an explicit method in class such as grandpa_a or parent_a for the 
one you want to call.
You could reopen the class and add the method where required.

Others:
Since you can get public methods of an object, i think you can go up the 
heirarchy and get the specific method. And then pass your message to it 
using send.
You could do a one time traversal and store a ref to the method.

Surely there will be other methods.
