Communication between two phones and vicc

[JackHunter0x3a]

Hello, I'm trying to figure out the architecture of this nice looking project made with so much effort.
Is it possible for this architecture to communicate between:
phone (android connected to reader) > = < cloud server > = < android phone

Where I use the <> characters to indicate that there is two-way communication between Phone A and Phone B.

If this architecture would work, then on the Cloud Server should I install ubuntu and run vicc and this two applications on Phone A and B it’s need to be connected to the server?

Does it work on version Ubuntu 20.04.6 LTS?

In reality, I imagine that I read the data through the first one with the reader and send it to phone 2, already phone two can use an emulator if it wants, or can it only read? but the important thing is that the Cloud host itself is correct?

This should work in a local network without cloud service:

phone + smart card emulator <-- (local network) --> phone + smart card emulator <--> real reader

All you would have to do to do this via the internet would be to add VPN on top so that both phones can communicate to each other.
