MCU RTU physical architecture

Below I show the Modbus RTU architecture that I want to create at the physical level. A short time ago some users showed me a draft of the connections (see diagram on the left of the photo) in which they specified how the connection should have been. Other users, on the other hand, advised me to use MCUs as Modbus needs the slaves to have their own unique id.

To the right of the photo, I drew a sketch of what I would like to do. Do you think the various connections that you see can fit on a physical level??

As for the software, I will use Python and the PyModbus library.
