Mnttech, its probably possible to have a system in which aisle lighting acticates only between usuable doors, but there's also flaws with that.
1. You want to already have pax at the door when opened to establish flow asap. So lights need to be already on when they're undoing their seatbelts. The chances of the door being unusable are mitigated by the time saved in having pax already there
2. If a door is usable then becomes unusable there needs to be a way for the system to "know" this. Too hard and too variable since the CC need to make that call. Easy for the crew to overlook the step of pressing a button for example in the chaos of evac.
maybe it could be done but the benefits don't seem to be worth the multiple ways it could complicate things.
definitely worth some research though.
