Your best suggestions to implement Google AMP ?

Hello Wonderful Community ! 

I'm interested regarding what's the best solution to implement Google AMP in a Codeigniter structure ?

In a nutshell, the concept is to have another version of your HTML (mainly) matching all the AMP specs and easily-access through a suffixed url like www.yoursite.com/yourpage/amp 
The specs : https://www.ampproject.org/docs/fundamentals/spec
For example <img tag must become <amp-img, image URL must contains a pre-url of a CDN, etc. 

How would you do that ? What will be the best solution ? 
I hope Cloudflare will have an automatic convert tools for that, but that's not the case unfortunately.

If some people here already implemented that, I will be happy to hear what choice they did. And if you didn't do that already, I'm interested about your opinion too ! 

Thanks a lot
