Aftermarket or retrofit fuse box?

Anyone ever retrofit a different cars' fuse box or power distribution box into their A-body? I have been thinking about doing away with my old system and putting in a fuse box in from a different simple system. I hate the stock power box in my 70 dart.... There are too many things wired in a series that it makes it damn near impossible for someone to diagnose a problem sometimes.

I need to rewire my entire lighting system from scratch since all of the old wires are garbage. They are all tied in with the wipers, cluster lights, yatta yatta. I just want a simple, I guess I would call it "modern", light wiring diagram.
