    Is there established a notion of `composition of quivers' perhaps not a simple \circ but rather \circ^A_B
    where A and B are subsets of the 2 quivers, perhaps related to props?

    Wouldn’t this also be related to 0+1 TQFTs and the composition of cobordisms beteeh ‘0-dimensional manifolds’?
