Hella/Behr blowers work great if the system is in proper working order.

The 4matic cannot be simply disconnected. It can be disabled, but if there's a problem with the seals (common), you still have a problem, and to remove the system you have electronics, hydraulics, different transmission, different engine sump, ... don't start with a 4matic if you don't need it IMO.
