Is A/B testing in AWS for static websites not possible using Cloudfront?

Question

I've provisioned the following AWS resources to host a static website (via Cloudformation):

• S3 bucket to store the website
• Cloudfront distribution for CDN (for reduced latency)
• Route 53 A record sets that directs traffic to the CDN

I have two completely different websites that I'd like to A/B test to see traffic behavior and conversions. Is it possible to configure A/B testing using the resources that I've configured?

This is what I've tried so far.

Bringing up the same Cloudformation stack for the second website doesn't work cause Cloudfront only allows a single distribution to have a particular CNAME. For example if my website is example.com, only one Cloudfront distribution can have that CNAME configured to it.

If I try to use the existing Cloudfront distribution there doesn't seem to be a way to split traffic to the two different websites hosted in different S3 buckets. Within the Cloudfront distribution I need to create a second origin and then a behavior. The behavior requires a path + precedence so all the traffic will get sent to one of the websites but not the other.

Is it not possible to configure A/B testing of static websites hosted in S3 with Cloudfront?

You can use a Lambda@Edge function to manipulate the request and then serve a different page using CloudFront.
