SLG had support for a DirectLight hybrid rendering mode. It was just Path render mode with a parameter set to 0. SLG2 PathOCL (alias PathGPU2) has also a control to limit the count of path bounces over diffuse surfaces. This works like a DirectLight integrator if set to 0 (1 is quite interesting too: very fast and still offer some GI).
It is trivial to add such parameter to Lux Hybrid Path ... the question is when/where add the parameter (i.e. wait for v0.8 release, a new branch, SPPM branch, etc.)
