I had no real intentions of naming it the Scooby Doo Trust, but even if I did I doubt I'd have any issues Hanna-Barbera over it.
My curiosity arises from what might happen upon my passing, and if my wife would want to sell the NFA firearms in the trust.
I know from my standpoint it's best to have the name simple and easily identifiable as connected directly to me, IE Greening Trust. But if I was looking to buy an NFA rifle, something with Ocksenshwrtz Trust on it wouldn't exactly trip my trigger.
I was only half kidding about the さむあり Trust, or something in the same vein. It's unique enough to not immediately turn someone off, and looks a lot cooler than Greening Trust.
