Red dot on Laser Designator

[Double Doppler 10]

I am curious to know if the laser designator red dot could be used on weapons as an aiming device.

I have observed the Laser Designator classes, in the configs in weapons.pbo, and it seems that the laser designatior dot comes under ammunition class, but would it be possible to use this (or a technique similar) as well as loaded ammunition at the same time, for aiming purposes? I have seen a camera that uses a red dot, but that works in the same way as the laser designator, you fire to display the dot.
