Could I flash multiple ECMs at once?

I was wondering to myself if it would be possible to flash multiple ECMs at the same time in the following manner:

- Set up Bi-directional communication with one ECM
- Copy the outgoing uni-directional communication to the other ECMs, ignoring any responses
- Flash to the bi-directional ECM

Are there handshakes that would impede this idea?
