I can make you a new nut PDQ as I have the tap I used for the one you've got. I can leave cutting the slit up to you if you want, though the cutter I have would probably go about that deep. You can measure the one I sent to see the max depth I can get, as it's easy to see where I stopped milling and went further with a bandsaw.

Ken,

I can't modify the current nut because if I take enough off to clear the trough I cut into the slit and I end up with two halves instead of a whole nut. If you could make me a new nut that would be wonderful, although I hate to have to ask you to do that.
I'm going to mock up the redesigned nut in aluminum without the acme thread. I'll make it a slip-fit over the acme thread just to test for clearances with the trough. I don't want to screw this up again. If all goes well with the mock-up, then I'll create a new drawing with the updated dimensions.

Sorry to put you through this and I'm eternally grateful.
