I tried a custom layout that did that for a while. I put the arrow keys in the centre (Qwerty's y, g, h, b), I think along with some other usually far away things. Then the letters needed to extend up onto the number row, so I made the function keys the numbers, and the numeric keypad the function keys. I used it enough to touch type at a decent speed, but I didn't keep using it for long, as at that point I was better off avoiding keyboards entirely. Numbers only on the numeric keypad would be awfully inconvenient for programming.
