If you put it where the caps lock key is, and turn your hand slightly, then you can rest your pinky on caps (now ctrl) and your other three fingers on s,d and f. I find this pretty comfortable.
The problem now would be C-a, C-z and C-q. I rarely use C-q (quoted-insert) and would use the right ctrl key; C-z (suspend-frame) is almost always a mistake and now annoying to press; C-a is pretty common, but easily reached with pinky and ring finger.
