Of course.

Also, can you change the channel order for 7.1 channel audio with eac3to?

Yes. Now:
6 = Side Left
7 = Side Right

Edit: It seems that when I change the channel order (-0,1,2,4,3,5), the resulting file still has the same channel order when I check with ffdshow.

Nope, the eac3to remapping works fine.
