This perhaps suggests a way of handling this in a more
general way in the future:

Add a slot to the typeobject which points to a variable-sized
array of pointers. There is one entry in the array for each
level of inheritance, and it points to a struct containing
whatever extra stuff you want to add at that level.

This would only handle single inheritance, but I think
that's all you can have at the C level anyway, isn't
