Hi, and welcome to the forums,
Single piston engines will most likely not come, as they are/were nowhere near popular enough to make them worth the cost of developing them. Also, please note that the engine designer is feature locked for a while.
Right now, the current level of transmission customization seems to be appropriate. It is not too complicated, and still covers all major choices. In the next few weeks, automatic transmissions, along with sequential transmissions, will be added.
