AMP + OneSignal

I have a very good friend who is a OneSignal developer that I am having lunch with next week and want to talk to him about AMP users still being able to use OneSignal web push notifications.

I realize OneSignal is not AMP compliant.

But, my thinking is that if the OneSignal WordPress plugin had a way to specify only one URL on a site where a user will be prompted to allow push notifications, and that page did not have AMP enabled and the Javascript was ONLY loaded on that page, would this work?

Then WordPress AMP admins could develop a image to sign up for OneSignal and link the image to the one URL that has the OneSignal javascript and prompt to subscribe.

Discuss it.
