Screen Mirror / Cast between 2 Android Devices via Bluetooth or Cable

A

AC Question

Simple explanation of what I am trying to achieve...

I have a Sony Xperia Z5 mobile on a 3 'Unlimited Data contract'
I have also just purchased a Lenovo Yoga Tab 3 Pro which has an inbuilt projector

I am going on holiday soon and would like to watch movies on a big screen/projector whilst I am away. (Will stream data online via YouTube etc)

My 3 contract allows me to use my unlimited data abroad which means on my mobile I can go online as much as I would like. However tethering abroad is not available and the internet access is only available for my mobile.

Therefore, I would like to mirror my mobile screen to my tablet (via Bluetooth or cable) to allow me to watch my films through the projector.
No WiFi will be available, therefore the connection must be physical with a cable or via Bluetooth.

Side not, I am aware of an app could Screenmirror but this limits the "mirror" to a browser windows, not allowing me to access other apps that I would like to project. Hence looking for a full screen to screen mirror

Can this be achieved in any way?

Much Appreciated,
Ell
