AFAIK yes, at least the way you are doing it, you can however change a MAC
adress before configuring the card.
ifconfig eth0 00:E0:7D:02:C6:0C
ifconfig eth0 123.123.123 netmask 255.255.255.0
So what i am saying is, you cant change the MAC address when a IP# is
assigned.
I tested it on my eth0 interface but without aliasing, but i doubt if that is
an issue here.

Down the IFC's, change the MAC(s), then configure the card and its aliases.
