The interaction with the street on the ground level is important. Granted some low rises or smaller structures (4-6 floor) range will be lost, but if the existing tower can somehow include a nice street to base interaction (retail/the right type of retail or shop), it could add a lot to the block.

I think the problem may be the rents. The mom and pop type stores are always the best, but typically you'll find some upscale boutiques. Not that there is anything wrong with that, but you'll find them kinda empty at times.

Ever walk into the Versace store on 5th? Its a ghost town in there.
