I have been playing with a very flexible and humanly usable cipher (not a verbose homophonic substitution) that can produce many different outputs for the same plaintext (here: "errare humanum est") such as these three:
olShedy Shedy lor otar otchdy ol Shey tchy lr op eey chy dy
sair al Shedy dar otal ytchdy ol Shey tchy dor chkchary chy dy
dair al Sholy or otar ytchy dor Shey kchdy ol chkchy or chy dy
"perseuerare diabolicum" can be:
cThy dair cheeeody oldy Shedy dar otar qoky okchody keor chey ted daiin Sheol
(I am trying to optimize the keys to match Voynichese better but convergence is slow.)
An entire Rosetta stone would be needed to figure out what this means (famous motto, Latin):
oain kchaly kedy Sholy chkchy cKhy or keotal ol olSheykeees soraiin
olShedy Shedy lor otar otchdy ol Shey tchy lr op eey chy dy
sair al Shedy dar otal ytchdy ol Shey tchy dor chkchary chy dy
dair al Sholy or otar ytchy dor Shey kchdy ol chkchy or chy dy
"perseuerare diabolicum" can be:
cThy dair cheeeody oldy Shedy dar otar qoky okchody keor chey ted daiin Sheol
