Batocera Boot On Lenovo 500e Chromebook

Is this possible. what challenges am i looking at for this? It is sat there being unused and thought it could be a good Batocera or Archos (emulator os) for myself and my kids to use.

I have spent hours and hours looking into this and have hit wall after wall. different things said etc. it is on the latest chrome os it can have. and in developer mode. but am now stuck.

any help and/or instructions on how to do it would be gratefully accepted.

Many Thanks In Advance
