Right, LDoms has support for alternate MAC addresses (ldm set-vnet alt-mac-addrs=...),
to have multiple MAC addresses on the same vnet.

No, alternate MAC addresses is not supported by the current Linux sunvnet
driver.

Maybe you can use a second vnet connected to the same vswitch. That way
your domain will have two MAC addresses on the same network (same vswitch)
but on two different vnet interface.
