This is a pretty cool project! You should take a look at this paper : https://arxiv.org/abs/1705.02012 . Using your heuristics to select the answers, you maybe able to generate some non fill in the blank questions. (All I saw was fill in the blank, not sure if it does other types of questions)

It also does true/false and multiple choice. Right now the text sample has a lot to do with what kind of questions it can find.
