I'm still interested in why you are concerned about "leaking" the MAC address? Changing the MAC with laddr will still leak the MAC but now it will be the one you created.
If you do decide to change the MAC to a long defunct NIC manufacturer. That is what I do for fun. Some of my 10G interfaces use Western Digital OUI, from 10base-2 era.
