Hi,
Can I perform surface Laplacian (current source density) and then do source localization using weighted min norm?

No, the minimum norm estimates requires the EEG in the original physical units.
The surface Laplacian can be used as a quick (and dirty) replacement for source localization, but it should not be applied prior to any more formal source modeling.
Use one or the other.
