No, surface shaders can only be evaluated by mantra. Geometry shaders (CVEX) are required to procedurally evaluate point or vertex color. The attribute vop and geometry vop evaluate cvex geometry shaders in geometry(SOPs) and dynamics(DOP) contexts. Surface shaders are built using the same langauge as geometry shaders, so it may be possible to recreate in a geometry context. Note that there are differences in how global variables work, and which nodes are usable.
This page isn't very much help for new users, but this is the node to use for building vop networks to operate on geometry in sops:
