I definitely would not change the oil system.. you probably have one of the best oiling system that money can buy. . it would be a major downgrade to the motor. I think I would spend a few bucks on the car to accommodate That engine.I am one of those that thought I would be better By going wet sump 3 years ago. now I'm spending more money to go dry sump.. . Your best bet would to do a motor plate. And K member. And stay dry sump my opinion only..
