Night landings themselves aren't dangerous, nor is landing on grass, or a combination of both.
BUT doing it with a "home-made" system that is not checked or approved, then I wouldn't go near it with 20 ft barge pole thank you very much.
It sounds like you do know what you are doing, but when you say there are 3 independant systems are they truly seperate? What happens if there is a power failure? Do you have battery or generator back-up? If so, how long will it take to kick in? What if you are in the flare at the time?
What are your maintenance schedules going to be like? Who's responsible for it. Will your insurance company find it acceptable?
There are a great many variables and potential pitfalls. Those are akin to poking the man with the sharp object, not the act of landing at night itself.
