While it is certainly impossible to prove this, what can be stated with certainty is that the two works have nothing to do with each other.

You have very strong opinions Antonio and at the same moment don't want to accept that they are just as speculative as many opposite ones. Naked women are stars? Prove it, show other works were naked women with fat bellies are stars 

An opinion that the Voynich artist was taking loose inspiration from many works - some herbal, some German astronomical book, De Balneis, Taccola, even some religious books is rather mainstream.
