Route via Aulnoye makes sense, but then since ES already runs a night train from Brussels to Praha, this one could better run along the dorsale wallon direct to Liege. And then why via Hamburg - seems a strange deviation unless heading to go to Scandinavia ?
Hamburg is not a huge detour and obviously there will be more customers interested in getting on or off the train there than Hannover or so. Also the tracks between Hamburg and Berlin are currently being renovated, so once those are done, the ride is probably going to be a lot smoother.
