If magnetic charge exists, it can flow.

Would the flow of magnetic charge produce a current that would be a source for the curl of B, in Ampere's law?

No. The source for the curl of B in Ampere's Law is the flow of electric charge. By duality, we would expect flowing magnetic charge to act as a source for the curl of E in Faraday's Law, i.e., it would become $\vec{\nabla} \times \vec{E} = \vec{J}_m - \frac{\partial \vec{B}}{\partial t}$, where $\vec{J}_m$ is the magnetic current and I have left out constants that depend on the units being used.
