i would say that you're wrong, but i'm not sure
that i have understood you correctly.

one thing is especially important.
in a vocoder the possible frequency content of the vocoded signal
depends on the filter configuration of the synthesis section.
the analysis section a129/1 is only analysing the input signal
and the synthesis section is producing the audible vocoded signal.
the vocoded signal is the mixed output of all filters in the
synthesis section. these filters have fixed frequencies and a
fixed bandwidth, no matter how the input signal looks like,
no matter how the analysis section looks like, the vocoder can
only output a signal at these frequencies.
consequently the only way to increase the resolution of a
vocoder is to increase the amount of filters in all sections.
then also the filters would need to be steeper in order to
increase the resolution effectively.
