Can I change my 1993 impreza's rear drum brakes to disk brakes?

My impreza has disk in the front and drum in the rear. I want to change the drum to disk. Should i? Can i? Link or explanetion on how please.|||you%26#039;ll need new/used knuckles with mounting points for the calipers. running the brake line from where the wheel cylinder was and swapping over the ebrake parts are the hardest part. i%26#039;ve done it so it is possible, just gotta find all the parts.
