Use layer-specific edge Sets from different graphs

[fafal-abnir]

I have two graphs, G₁ = (V, E₁) and G₂ = (V, E₂), that share the same set of nodes V but have different sets of edges E₁ and E₂. Is it possible to design a GNN with two layers(for example 2 GraphSage layers), where the message passing in the first layer uses the edges of G₁, and the message passing in the second layer uses the edges of G₂?

Yes, I believe it is by using edge_index1 and edge_index2 represent $E_1$ and $E_2$, respectively, and making sure node indices are consistent between the two graphs.
