Well, even with the many assumptions that you made in terms of spelling, you can see that this fails the test, unless in Greek we have some celestial body or constellation called "birdcage" or plant called "estate", etc. That's the problem for the theory of Voynich labels as plain designators.
This has been attempted by linguists before, most notably by late Prof. Stephen Bax, and they have not been very successful with the labels.
