Braided $n$-ary coherence conjecture for polyadic tensor categories

Let $\mathcal{C}$ be a braided semigroupal polyadic category with an $n$-ary tensor product, an $n$-ary associator $\scalebox{1.15}{\textsf{\upshape A}}^{\left(2n-1\right)\otimes}$, and an $n$-ary braiding $\scalebox{1.15}{\textsf{\upshape B}}^{\left(n\otimes\right)}$. Assume that the associator satisfies the $n$-ary coherence conditions giving the canonical reassociation isomorphism on $3n-2$ objects, and that the braiding satisfies the polyadic analogue of the hexagon identity. Braided $n$-ary coherence conjecture. Under these assumptions, every diagram containing $\scalebox{1.15}{\textsf{\upshape A}}^{\left(2n-1\right)\otimes}$ and $\scalebox{1.15}{\textsf{\upshape B}}^{\left(n\otimes\right)}$ commutes.

This is the braided extension of the proposed $n$-ary associator coherence principle, analogous to the role of the hexagon axioms in ordinary braided monoidal categories. The source gives no evidence of a proof or refutation.
