I thing this can be done in compositor only. Try make shadow catcher in different render layer by this tutorial and combine all together in compositor. [this video]

Yep, sounds like you don't really know what you are doing. That is not what shadow catcher is used for. See [this video]

This question and its answers [LINK] give nice ways of creating plane shadow catchers that make the CG objects "interact" with the HDRI world. My question is very similar, but different in the sense that I don't want the HDRI world ground to catch my shadows. Instead, I want a transparent plane to catch my shadows. Something similar to this short video tutorial [this video] , which succeeds under lamp lighting, but fails to do so under HDRI lighting.
