Tried it on my own network
It is easy to change the Mac Address
This is what I did
Used an Atheros USB 2.0 Wireless Network Adapter
Windows XP sp2
From the device manager
Select properties on the adaptor
Change to advanced
Select Network Address
Type the address you want into Value
Eg 11-22-33-44-55-66
(Note remove the dashes this address now = 112233445566)
Enter the address 12 alpha numeric numbers 0-9 a-f
Click ok
I entered the same address as one of my working wireless adaptors
What happened next?
The router connected the Atheros USB 2.0 Wireless Network Adapter
Gave it the IP address assigned to the other PC
The other PC was kicked off the network
Try it yourself
