Upgrading wifi card

[MiamiC70]

Is it possible to upgrade my mid 2011 MacBook Airs wifi card to be able to connect to 802.11 AC? Also, would this enable continuity and handoff under Yosemite as the newer wifi card have the BT4.0?

Would this be the correct part# BCM94360CS2?

have done a lot of research about it but could not find much info.

would the BCM94360CS2 be a simple swap ?
