I don't think you can construct this. What you are describing is two single slit experiments, side by side.
In other words, if the partition runs the full length of the path, one slit or the other will be isolated from a source of electrons (or light, or protons), and will emit nothing.
You can never have two independent, isolated pathways.
It’s called the tunneling effect.
It can tunnel through time or space or energy barriers. Not every time, but enough times to make you throw out the baby with the bathwater.
True, which is why I am hesitant to believe that electrons have some kind of “intelligence”, or hocus-pocus, to detect observation and behave accordingly.
