Upmixing a stereo pre-master to a LCR master in Cubase?

Hey everyone, I just received a stereo pre-master (no access to original stems) and the client needs a LCR Master for a film festival. Just wondering if this is possible in Cubase and if anyone knows how to do it?

Thanks in advance!

Found a plugin called NuGen Halo and I think it should do the trick!
