An idea for a kontakt instrument

I'm a radio producer and I always thought on having a virtual instrument for kontakt like Mysteria or thrill (vocals but not dark) where you can manipulate "vocal chants" as background for Radio promos or even for live recordings. Example: the live recording of "We will rock you" the stadium crowd chant supports the lead singer and that chant makes it sound gigantic, so if I'm producing a concert spot where I need the crowd to back up as "background chant" It will be great if I can open kontakt and choose some consonants and vowels that sound like the whole arena is singing...or a small venue..just an idea.
