I think your last sentence is what I was getting at.

One could have a 7-bit canonicalization that does the same sort of thing MIME does, I suppose, at least in terms of content conversion.  Not having given it much thought yet, though, I suspect doing this at the MIME level is more likely to be successful rather than at the message level, which is where DKIM lives.

I could swear I heard that idea presented recently...
