Acer Chromebook screen replacement with an iPad

Crazy thought…..

I would like to connect my 2019 iPad Air to my 2017 Acer Chromebook. I would like to use my Chromebook as a portfolio/case/external keyboard. Has anyone ever done this or made an attempt?

1. The iPad and Chromebook have similar sized screens therefore they would fit together with little modification.
2. I am puzzled as to how I would connect the two with a simple Apple proprietary Lightning Cable in order to still have the perks of an iPad.
3. How do I get the keyboard and battery to communicate?

This would essentially repurpose the Chromebook into a LineDock or janky Magic Keyboard. Thank you in advance.
