I converted a StumpJumper Sport bike to use an 8-speed IGH. To keep it as simple as possible, it uses a single chain wheel up front. It is nimble and fast, surprisingly so. I got lucky picking that frame for the project.
I put some drop bars on it but did not care for them, so I took them off. It was kind of surprising how many things had to be changed to go from flat bars to drop bars, and how much it all cost. It was a total waste because I went back to flat (North Roads) bars.
I once put flat bars on my road bike. That sucked, too. The frame geometry was not good for upright riding. Neither was the saddle.
If you do it, chose the frame carefully.
