I'm remodeling the kitchen. Our sink is a standard 7" deep sink, but most cool sinks these days are 8-10" deep. I would probably want to keep the existing configuration with the double bowl and disposal. It looks like I could maybe squeak out an extra 1.5 inches by shortening the tailpiece below the sink. I think modifying the plumbing stub out so the trap arm could be lower would be a pain because this is an exterior wall below the window.
Here's a picture with the measure up to the bottom of the sink.
