Indo Aryan Origins of Voynich .. ?

Erromintxela is considered to be a pidgin between Caló romani and basque, not Kaldarishi, which is a variant of Vlax Romani, the language spoken by the gypsy in Eastern Europe. 
Whilst it's true that some gypsy tribes start to appear in the Basque country towards the end of the 15th century, we have no evidence as to their language. 
In any case, the languages you describe didn't exist in the early 15th century, the gypsy's would have been speaking a very different and older version of romani.
