You would have to either

a) replicate the edits with something that can edit 5.1
b) demux and replicate the edits on each mono wav file, then reencode to 5.1

Then reauthor the new audio back in, either from scratch, or using something like ifoedit

It is not practical to try and recreate 5.1 from stereo.
