Are you planning on landing/departing from an airport under SVFR i.e. Channel Islands?
It is my understanding there (present IMC holder) that they will not clear you SVFR unless you have BKN800 or better, and 3000m Viz.
In Class D, I've had SVFR before at the viz minima (1500m, which was practically instrument flying) and at 800ft when I shot the ILS and broke away once visual, and continued to my destination in SVFR / VFR outside controlled airspace.
Obviously, you need to adhere to the clearance minima, which will likely be the biggest problem, and low flying over congested areas.
