Even if your brakes aren't smoking, ducts will help keep your temps in check and your pads will last longer. Plus, it doesn't take a lot of get heats into the brakes and its not very tricky. Not like trying to get heat into conti scrubs on a cold day.

Wouldn't do it on my E90...but the ducting allows me to run the Stoptech Street pads in cooler temps on my E46. They keep the pads temps in a reasonable range that prevents them from transforming into a useless brick of pad material. I wouldn't even think about it without the ducts.

If you route the ducts carefully, you can go lock to lock without tearing up the hoses. If you do wear a hole in the hose...just fix it with some duct tape. I think DDing with brake ducts is doable. I might be concerned about rain...probably not an issue especially if the brakes are warm/hot.
