Generally speaking, mental ray is fairly finicky about versioning and compatibility. Usually shaders need to be re-compiled for each version of mental ray, and only on rare occasion does an older compiled shader work on a newer version of the renderer because of all the subtle changes to the code.
Taking a .dll from a newer version of mental ray (Maya) and trying to use it in an older version (Softimage) is not likely to work. Just after Softimage was EOL'd, mental ray went through some significant core changes to greatly improve performance. I doubt what you're asking will work.

Hello, I?ve got a naive question about MR for Maya: Can Softimage read those .dll and work with them? Like, point softimage to a specific folder in preferences and will it pick up the Mental Ray code to use as renderer? Thanks. -- Portfolio 2013 <http://be.net/3dcinetv> Cinema & TV production Video Reel <https://vimeo.com/3dcinetv/reel2012> ------ Softimage Mailing List.
