This would be more of a stock footage solution that a preset. Presets at this point cover various grading options for changing the colors of your footage, and then these effects categories: Optics (for light effects), Neon Light (for lightswords and other light effects), Muzzle Flashes (for, well, muzzle flashes), and Particle Effects. Cross-hairs don't really fit into any of those categories.
Not to say that they can't be done. You can easily import one of the old AlamDV plug-in crosshair overlays and composite it into your footage that way.
