I doubt it will work. Every EEPROM parts have slightly different command
set/cycle for programming. You can not just change the ID and expect it
to work.

I am sorry that I can't do it for the moment. Programming EEPROM
needs a little bit of trial and error. You can try download the
datasheet from SST and modify the 29EE020 code.
