I know you've probably come up with a good control system but here's an idea I had.
To choose the area you want to hit in, use the mouse so you can actually hit anywhere. Backfoot will be the W key and S will be the front foot key while left click is too hit the ball. You have to drag it to the channel you want to hit it in (it's in a V like in BLIC) and hold (so it doesn't stay in the original place and so you can now keep it in the place you want to) down the left click and click it again to hit the ball. Also, since you are using the mouse, you can change your shot at the last moment. Obviously, the shot will most probably not get maximum runs if changed at the last moment, just like in real cricket. Plus, along with holding W/S, you have a choice of three other keys for a defensive shot to just nudge it for a quick single, a normal shot and a lofted shot, like in BLIC.
I think this might work well. Some views on this would be nice.
