Could we have more stops like Bourdon, Bombarde, Clarion, Principal, Clarinet, Salicional, and more string and reed stops with some mutations. And could the stops be at different pitches. Like there could be a 16' and 8' Bourdon, or the diapason could be at a 16', and 8' pitch. There could also be some more pitch varitations for the stops like a 16', 8' and 4' trumpet. I made a list with more common stops and pitch varitations for already existing stops that I think would make great additions.
Diapason 16' addition
Trumpet 16' and 4' additions
Tuba / Tuba Mirabalis 16', 8', and 4'
Trumpette en Chamade 16', 8', and 4'
Octave 4'
Principal 8' and 4'
Clarion 4'
Chimney Flute 4'
Spitzflute 8' and 4'
Bourdon 16' and 8'
Harmonic Flute 4'
Oboe 8'
Subbass 16'
2' Fifteenth
Bombarde 32', 16', and 8'
32' flue stop for more variety.
More string stops like Violone, Viola, and etc.
Mixture-like stops like III Scharf, IV Grand Tierce, Cornet V, and etc.
