1 & 2 cylinder engines

As per the "what will be in the game" thread I3 engines are the least number of cylinders planned.
As the tycoon mode is going to start post WWII (afaik) can I suggest that flat twin and single cylinder engines be included? Flat twin engines were very common in the 40's and 50's and have come up now and again since then. Single cylinder engines are probably less important but they have also made several appearances throughout automotive history.
