thanks for the link to the Arkel site, I do like the shopper bag.

I went to the Bike Doctor and looked at some bags and if I had the money I'd have bought the Ortlieb urban bag that turns into a messenger bag. I liked their shopper bag, too, but the attachments wouldn't feel good against me, and would look weird if it's facing out.

I've found some reviews of the Detours Toocan, and some of the cons are that it's heavy due to the rubberized bottom and the fact it rattles or comes off the rack easily. Same with the Toto bag, the fact it's only fastened by a magnet leaves it a bit vulnerable if it comes off or if I have the unfortunate experience of coming off a bike.

I guess I'll have to resign to the fact I won't be able to have it all, but the Ortlieb has come the closest so far.
