It is possible with a trick: set the partition between eye and light passes to 0.0 and render with PATHCPU. The result will be the rendering of only light passes (because the eye passes are set to 0%).

For instance:

Light tracing is only done on the CPU even when using OpenCL rendering. Rendering only caustics is a very specific and very fast task, CPUs are good enough.
