Can it be done without a "Rosetta Stone"?

[Ruby Novacna]

In parallel of research  of documents containing the key, we can already check all alphabets proposals made to date. If I understood among amateurs of Vm there are people who have mastered programming. They could create a program that would take into account all the variants proposed of alphabets and then compare with the proposed languages. Already we would be fixed if it's from the Latin, Greek, Arabic, Slavic, from Nahuatl or not. 
But maybe that's not a good idea, as this may break the dreams of some one go (I mean me).
