In addition to the other comments on difficulties of such analyses, an additional difficulty may be the type of inscriptions in the corpus. We understand Linear B, for example, because it is early Greek. But the texts are not narrative prose or poetry: they're administrative records, mostly lists and inventories. If Linear A texts are of similar types, then trying to decipher the language from them alone may be challenging or impossible, unless it can be linked to a known language: the forms of speech used may simply be too limited. Trying to understand English grammar by looking only at bare financial statements would likely be extremely hard.
