Editing on phone with Chromecast

Hiya,

New owner of OneR and I have been fooling about with editing on a phone.

Works pretty well hooked up to the camera.

What would be nice is if this setup could use Chromecast on a TV as a preview monitor.

Not sure how this would work as both the Bluetooth and Wifi are used by the phone to communicate with the camera.

Would it be possble to hook the phone to the cam by USB?

Then the Wifi could be used to send video to the Chromecast. Once hooked up, the whole screen on the phone could then be devoted to the editing interface. Maybe a 'virtual scrub wheel' could be implimented to move back and forth through a clip?
