Honestly speaking, although i have yet tried the new Dupins (which by the way, there are 2! Ghys and Roland), i have never felt impressed by the 2 older ones that i have tried. A renowned expert oboe maker/repairman from the UK worked on my oboe (i do not want to say his name because sometimes i am not sure whether he wants his work told of at times...haha...there aren't that many anyways so upon slight investigation one would quickly find out). Yes he re-bored it so that the higher register would be higher and sit on itself more. I am not sure how much he actually re-bored but certainly it is not a simple matter of making it bigger but having changed a certain dimension as well. I also changed the size of the octave pits. Certainly this has improved the upper register but i also find that it has it's compromises with the lower. I remember the lower register spoke better and had a warmer sound before.
On the case of the reeds... while i am not sure whether your assumption is correct, i do find that at the end of the day, for practical reasons, the internal volume usually comes to a similar produce. For example, i now make 2 distinct types of reeds for my Buffet, one with 45mm chiarugi 5 (narrower glotin) staples, and one with chiarugi 2(loree)/2+(rigoutat) 47mm staples, with the same -2 shape, and both work well at the same pitch. Ke Xun reeds on the other hand, which i purchase once every 2 months to have gather a certain amount of security for rehearsals and concerts, uses a smaller chimney staple but ends quite big at the bottom and these at 47mm work very well too at the same pitch. (In fact my 69mm reeds often fall flatter than the 72mm ke xun reeds.) And i sound the same on all of them!
