mris_expand may do what you want. You can use it to shrink or expand the points on a surface by a fixed percentage or a fixed distance.

Dear Freesurfers,
After running recon-all, the wm surfaces are too close to the pial surface, some gray matter is segmented as white matter as seen in the attached picture (red cross: a bigger cortical part is included in the white matter). How can I shrink the wm surface?
Thank you for your help!
Andrea
