I might have misunderstood your question.
x1, x2, … would be the inputs to your model which are just summed.
Would you like to pass these inputs separately to the same layer?



 pdu:

how can I add a layer of output nodes to an existing layer?


x = self.fc(x) will store the output activations in x. You can pass it to a new layer just by calling self.fc2(x). Could you explain the first image a bit, as I’m still unsure about your use case?
