  We investigate the properties of a weak link between two Rashba-based
superconducting nanowires with geometric misalignment. By applying an external
magnetic field the system can be driven into a topological non-trivial regime.
We demonstrate that the Josephson current can be modulated in amplitude and
sign through the variation of the applied field and, remarkably, via the angle
controlling the spin-orbit locking mismatch at the interface of the nanowires.
The proposed setup with misaligned coplanar nanowires provides the building
block configuration for the manipulation of coherent transport via
geometric-controlled mixing/splitting of interface states.
