Go for it, no reason not to try it. Its easy enough to change the location of the brake levers and shifters. Why don't you mount them up that way for a week, then mount them up in the more traditional way the following week. The only thing that I see that way cause some discomfort is that in the location you want to mount them, the bars are curving, while the brake levers will be straight. This will cause the levers to stick out some and perhaps not be an easy reach from that part of the bar. Of course it could just as likely be fine and you'll find them comfortable. The upside to that location is, at least for myself, when I'm rolling downhill at speed that is the location where I place my hands. That widest area of the bar I find I have better leverage on the bars for stability, but with my setup I don't have the brakes readily available, your location would solve that.
