You can build a character that is primary a street samurai, magician, physical adept, breaking and entry expert etc. and then pick up a deck and some hacking skills on the side.
Devices (such as elevators and lights or maglocks and cameras in public areas) are probably not slaved to a host (due to the security risk) so they will only defend with some 4 dice anyway.
Devices (such as maglocks and cameras in restricted areas and drones) are probably slaved to a security host (so that the security rigger can get a direct connection to them no matter where in the world he is physically located) and will thus defend with host ratings if you fight them out on the grid. But since you are hacking from AR you have the option to physically get very close to them. Establishing a direct connection with a wire from your deck to the device. The device will now only defend with some 4 dice and if you get a mark on it you will also get a mark on the host. With a mark on the host you can now enter the host and get a direct connection to all other slaved devices (ignoring host ratings).
Going onto the premises might require a lot of non-hacking skills. Maybe social engineering to get pass guard checkpoints. Stealth. Mundane weapon skills. Meat world initiative.... - but you you don't really need to focus so much on your mental stats or expansive decks. Think of the AR decker as an "aspected" hacker

A dedicated VR decker (or TM) have enough dice to toss around to sit in their apartment or out in the rigger van, hacking a device out on the grid that is protected by host ratings (possible using edge). With a mark on the host he can enter the host and get a direct connection to all slaved devices. A dedicated VR decker (or TM) will also have enough dice to throw around to dig deeper inside hosts. Going into the foundation or extracting pay data files (stuff that a AR decker hybrid cant really do). This decker would focus a lot on mental attributes. High hacking skills. Expansive deck....
Two different play styles.
