Hendrik,
I think you can try some of these variants:
Head S12 have a model N100 which is especially designed for very snug fit. After that a boot fitter can cut some parts of the liner (actually it is a plastic between the liner and the shell). I dont know where you can find these boots but Head S8 are available in shops\ebay and are narrow both in heel and forefoot.
Lange should be very narrow but I simply cant find these boots in dortmund
Nordica I found are very narrow in the heel area and quite wide/normal in the forefoot. Especially The Beast model which I have has a great fit for my narrow heels. They also have additional 2 plastics which can be placed on the back of the liner to fit the heels even better. Apart from that, they have spoilers which can help if you have thin calf. I undestand what do you mean by "my calf starts were the boot ends" - I am the same like you! All this things didnt help so thats why I asked for new holes for mu upper buckles! And there he messed up a little making the holes with 4-5 mm difference for the left and right boots. Actually now on the left boot is very hard to use the new position of the buckles and I will glue a scotch tape over some of the holes.. but the point is - we all have different/not standard feet

Atomic, Technica wont fit you I suppose, Salomon (Xwave9) are also wider in the heel (although i liked the flex of the boots). May be the Spacecraft (I am not sure if it was the spelling, the race model) can be narrower.
About the difference you mentioned. How long are in centimeters? For ex mine are 29.6 and 29.9. Your number will confuse you if you try to use it on your ski boots. Try to measure them at home or in the shops there are some shoe-meters (I dont know how they are called, you step on them and measure your feet). With grinding and cutting the shell and liner the boot fitter can compensate few mm but for 9 mm I am not sure. It depends on the width of the shell`s plastic which is different. If you cant find good boots at your town you can go to the shop (or to other shop with boot fitting service). There they will recommend the Nordika Beast I suppose but you are not obliged to buy them. Try them and if they pass and you just have pressure on the toes on your right foot you can ask if it is possible to grind 5 mm front and may be few from behind. Then you should make a custom insole and this will "give you" anoher 1-2 mm space. If you feel all the boots uncomfortable may be it will be better to go for "Schaumschuhe" (but as this is expensive of course should be your last variant)
I am by no means ski-equipment expert, I just share what I have found during my search and Yes Benna is right, The ski shoes are the most important thing from your equipment and travelling few hundred kilometers can be worthy in long terms (of course it depends on the time you spend on skiing
