A typical 4-reed Cajun box has the following reed configuration for
each treble note:
1 main reed
1 reed detuned from the main reed for tremolo effect (typically
tuned sharp)
1 reed an octave above the main reed, not detuned
1 reed an octave below the main reed, not detuned
Note that only one of the reeds is detuned, and it's at the same
pitch (or close) to the main reed. Putting two reeds an octave apart
out by the same number of cents will put the octaves of the detuned
reeds out of tune with each other, which may be more tremolo than
you want.
Following that setup might get you as close as you can get on a
harmonica run through an effects unit. (other accordions will use
variations on the above, with fewer or more reeds, different amounts
of detuning, etc.).

By running 2 effects boxes together one can get an approximation of
a cajun squeeze box. A Harmonic Octave Generator (HOG) adding 4
octaves (no fifths or thirds) plus a Detune effect from a Digitech
RP 200 (about 18 cents sounded "wet" enough) . Won't replace a
squeeze box, but still cool.
