Automatically replace composite Keras layers with the individual ops?

I want to convert this composite model with this hierarchy into the individual Keras ops so that it can be converted to another format.


Is that possible to do automatically? You can get the nodes and connectivity of KWSTransformer using KWSTransformer.layers[n].outbound_nodes. But only for non-composite layers. There seems to be no way to get the underlying nodes of ConvolutionBlock?
