Open multiple Unity external .exe file from a script

Hello Dears

I have to make multiple Executable program for each menu.

SystemMonitor.exe
Information.exe
History.exe
System.exe
Settings.exe
Utility.exe
AlarmMonitor.exe​

And then, call each external .exe file from a script.


I know, it is possible to create it in Unity by using "Process.Start " method.
(by adding using System.Diagnostics;)

In terms of optimization and maintainability, is it right structure ?
I know, we can make multiple prefab for each menu in the single exe program in Unity.
Or we can make multiple Scenes for each menu.
However, I am making different architecture for my project. but I am not sure this is the right way.
