It may be reasonable if you don't expect anyone to connect the device to an ethernet port, but in that case you could save much more by removing the ethernet chip and the socket along with the eeprom.
Really, any machine without a fixed MAC address is a huge pain for users, just google for "pandaboard mac address" to see how much work this has caused people.
