That will not work - the IP stack is smart enough to route packets to *any*
of the local IP addresses via the loopback interface, lo.

Are you simply not happy with lo, or are you trying to prove that the NIC
hardware works, or something else?

The book

Alessandro Rubini & Jonathan Corbet, Linux Device Drivers, O'Reilly, ISBN
0-59600-008-1

contains a pair of dummy network drivers playing the loopback game without
getting out of the host.

IMHO, you need another computer to test traffic out of the NIC.
