Non-simply-laced fusion conjecture for Weyl modules

Let ${\mathfrak{g}}$ be a simple Lie algebra, let $\lambda=\lambda_1+\cdots+\lambda_n$ be a sum of dominant integral weights, and let $c_1,\ldots,c_n$ be pairwise distinct complex numbers used to form the fusion product. Non-simply-laced Weyl-module fusion conjecture.

$$W(\lambda)\simeq W(\lambda_1)\ast\cdots\ast W(\lambda_n).$$

This extends the corresponding fusion-product result from simply laced Lie algebras to the non-simply-laced case; the source gives no resolution.
