Classical music isn't a well-supported format on commercial radio. There was a commercial classical station serving the Philadelphia market (currently 95.7 Ben-FM) until it was sold to Greater Media (which Beasley now owns) in 1997. Although it would allow Temple University's WRTI to return to jazz full-time, I wouldn't expect Entercom to flip any of their stations to Classical music.
In fact, most classical music radio stations are non-commercial and are usually located on the non-commercial band, although some can be found on the commercial band but are operated as a non-commercial station. There are some commercially-operated classical radio stations that exist or have existed, such as the WBACH network in Maine which was shut down on February 19, 2017, and 95.5 KHFM in Albuquerque which is being donated to a non-profit operator who intends to convert the station to its non-commercial status while preserving the classical format on the station as part of American General Media's acquisition of Univision's Albuquerque cluster.
