Traditionally the FS responsibility is pass coverage while the SS would come up in run support. What Denver had was two traditional SS and no true FS. Kennedy was SS and Lynch was FS. Ferguson is a better option at FS than Lynch or Kennedy.
A lot of teams have converted CBs who can cover and hit into FS. The Patriots converted Eugene Wilson from CB to FS. The Ravens converted Rod Woodson from CB to FS. I believe the Rams converted Aeneas Williams from CB to FS. Dwight Smith was a ballhawk as a FS in Tampa Bay.
