Like XeoRli already said, nothing fits your needs as much as a custom config.
But i'd start with some Basic things like optimizing all ingame settings and then try to build your own crosshair and viewmodel.
That should be the most important things. Next i'd focus at some launch options that could optimize you game experience.
And last but not least : Your OWN Buyscript!

FOV/Viewmodel :
