If you use sox compand, with a profile like "Film standard" in AC3 Dynamic Range Compression, you can finish with max peak at -11 dB, and you need Normalize after.
I think is better use sox compand over the 6 channels and after use eac3to with -downStereo -normalize.
Also, if compand is used over each channel, you can improve the dialogs volume in Center channel. If compand is used over the downmix the dialogs can be masked with global volume.
