Is it possible to revive Classical Latin as a language of ordinary speech?

It is unlikely that Classical Latin could be revived as a language of ordinary speech. 

Classical Latin was the language of ancient Rome and was used for literature, law, and administration, but it was not a spoken language for everyday use. The structure of Latin does not well support the modern-day needs of commonly spoken languages.

It might, however, be a fun hobby to try to speak Latin in the modern world. If you are interested to learn Latin, there is several places to start with.
Google Translator for example can translate several modern languages to Latin.
