There are a lot of cool experiments happening like this, both principled and from intuition

Ex:Label prop following non-local jumps ("metapaths") based on community detection (network-of-network, ...) or other shapes. Same thing for what constitutes a feature.

Michael Bronstein's papers (and talks!) are often in this vein, in the mainstream, leading, and quite accessible, so would recommend starting there..
