This sounds like a nice project, with plenty of scope for creative thought.
The frame builder Tony Oliver was always enthusiastic about braze-on centre pull brakes, he has a discussion in his classic book Touring Bikes. I guess you can add Paul and the Dia-compe/Gran compe to the list of such brakes.
If you are considering Kelly Take-Offs, then you may like to look at Gevenalle brake/shifters and the Dia-compe wing shifters.
You could add an inner front pump peg to allow a Zefal HPX pump to be carried under the top-tube without the need for the usual velcro strap in that position. If the bike is to be for fast touring, then you might want to at least get braze-on mountings for a rear carrier that could be added instead of the saddlebag frame.
Can you get a test ride on a Rohloff-fitted bike? It would be a pity to go through all this planning and then not like it ;-) I'm not sure there are great solutions for gear shifters with Rohloff that fit drop handlebars.
