A little research shows the V2500 is about 900 pounds more per engine than the -217, according to Wiki. Add in the pylon flaps, structure improvements and certainly over a ton-plus total at the wrong location.
High compression turbofans are heavy, an inescapable fact. Also, a reason reengining the CRJ series is a non-starter.
