I still see ENTER and DELETE horizontals in there as well. Every key above them apart from /? is already available as 1.5x, either horizontal or vertical. You could rotate them, I guess, but I don't see what you'd remove them for.
Yes, ENTER and a few others are in there twice, but 1.5x and 2x keys are very different, and these are essential keys. I don't want to leave someone without a backspace, for instance, and that's a key common in both 1.5x and 2x size. I'd like a 2x shift as well, but then we either have to add keys which ups the price, or replace ENTER and make people buy the numpad.
