Sharepoint Online: How to display internal corporate websites, without HTTPS?

Question

We have several internal web applications that do not require the HTTPS protocol, as they are purely accessible internally within our intranet. Obviously with Sharepoint Online, our websites will not work.

Is there a way to "mask" the http protocol inside an iframe or some other web part that will allow us to by-pass the https requirement?

Yes, I understand accessing Sharepoint outside of our network infrastructure will not allow users to use these internal websites, but that's ok, as staff are only allowed to use them internally. Thank you

Even if it will be just usual site I guess that browsers will alert the users, that some part of content goes through http on https page, here is an example - [https://stackoverflow.com/questions/18327314/how-to-allow-http-content-within-an-iframe-on-a-https-site]. So even if MS allows this, its easier to just have this certificate, than without it, the other thing that inside your organization you can use self-signed certificate, just to have "https".
