not deep in your project, but messaging is the route to go ...

the iFrame sends an event along with some data and parent window receives it ... this works bidirectional ...

in fact @MaxZieb wrote an extension that can connect hypeinstances... Hype Global Behavior (Custom Behavior Extension) ... this may help too

I think this would be fairly tricky to do and require custom code. Of course it is feasible, but here are some specific challenges to overcome:

you would need to animate something that could be scrolled anywhere on the screen to a position fixed on the viewport. Basically I'd look at the element.getBoundingClientRect() method and then probably have another layer that is positioned via fixed that interprets these coordinates and animates something to scale in
you'd need to pre-load content or have some sort of "cover up until loaded" strategy to make it seamless when content comes in. It may be worth it to potentially not use iframes, since it is harder to know when those are fully loaded and perhaps use alternate scenes. This could help with scrollbar management as well.
You'd need to make sure any manually changed data gets reset properly, either in just clearing states or returning to old states.
