Can Hollywood Orchestra Voices facsimile John Williams-esque choral pieces?

This choir is part of the Valentines Day sale and listening to demos of it, I get the sense that it is mostly a more Shore-esque choral inspiration. But I wonder for anyone who has it, can it also get more of the epic Ahhs and Ohhs of something with the energy of Duel of the Fates? Either or, I would buy it for the fantasy aspect of it and the Tolkienian Elvish phrases, but hearing something of this may make expedient my purchasing this library.
