I think IP takeover is enough.
If you want to use MAC takeover just for the problem of flushing
ARP table, then maybe there is a easy way to do it ?
when machine B takeover machine A 's working IP address, broadcast
its new ARP to every machine in LAN ,include client and router.
To broadcast a new ARP, you may write a small program, or just
use "ping" . If you ping a Null  ip address in LAN , it will broadcast
ARP automatic and flush client's arp table.
I have test this on  many machine.
