Hi, I'm thinking of changing my drop bars for mustache and I'm thinking of trying something. I want my main position to be more upright, and have my brakes and shifters there. But also have an aggressive option.

I'm thinking of using mustache bars possibly flipped and putting the brake levers and my thumb shifters(they're modified to fit the larger diameter) on the ends, like a north roads bars. I'd keep my long stem and I'd only use the front bends for headwinds, climbing etc.
The reason I'm thinking mustache instead of north road is so I'll still have the way forward bends to use. I know drop levers are designed to go on the bent part of the bar but I could still use them on the straight part, right? Any other issues? Anybody tried this?
