I have never seen an i2c device unable to change the address.
If you still need it then look at an i2c expander

Would like to get multiple nanos to network without extra hardware and without eating up all the memory. They would be using their i2c buses as master so can't just set the extra nanos as slaves. Softserial is very resource intense. Trying to leave the hard serials for debugging. This seems like a simple option rather than writing my own protocol.
