We can imagine a lot but the closest worldline of what you describe is the Omega attractor field (-0.275349%), everybody is alive including faris' father, ruka is a girl, SERN seems to not being an evil organisation (not sure) and we know the time machine exist in this worldline but we don't know anything about it.

Kurisu in the movie manage to use the time machine without changing drastically the worldline for a simple reason: Nobody in the future know about the existence of this machine.
