it'll be mono, and more seriously it's likely to have very little bass,
as bass guitar and kick drums and the like are often panned close to
you could work around that by, before summing the L and -R channels,
filtering out the low end from ONE of the channels.

otherwise just amplify one channel by -1. Then mix the two channels
