Answer 1

Answer: No

The important part: FlexStack is the name of the stacking technology used by the Cisco Catalyst 2960-S series of fixed Ethernet switches. FlexStack is specific to Cisco Catalyst 2960-S switches, and only Cisco Catalyst 2960-S Series Switches use FlexStack.

Longer Answer: No, because they use different stacking protocols and different physical cabling to do so.
