I'm not too sure about how easy it would be to use a non-planar sail to redirect photons in the direction required to constantly build forward momentum - but a photonic "wind" turbine used to power a quantum dot emitter array might be able to do something.
There's an omni-directional wind turbine (https://newatlas.com/2018-dyson-award-winner-o-wind-turbine/...) which sort of encapsulates what I'm thinking of.
