Except a commlink can't run autosofts without a program carrier, and even then it wouldn't be "integrated into the sensors" of your character. Don't forget, a sensor array starts at a minimum of 2000 nuyen, but is included with all drones and vehicles for less due to mass production.
Can it be house ruled? Sure, but why would you want to? The mechanics already exist for how metahuman characters interact with smart weapons, and you need a smart weapon and a smartlink, either in a visual device or installed as cyberware. Seems like a no-brainer to me, what with the everything has a price theme of this edition.
No such thing as a free lunch; if I could run the software off my link and not have to buy expensive gear, why would I choose any other option?
