I just wanted to refer to those simple shutters found at old box-cameras, when you hinted at that video.
Yes, that principle of flip-flop shutters was popular. In their most elementary form it meant that the release button/lever had to be activated in alternative directions with successive exposures.
Have a look at patents, you might get some ideas for simple shutter solutions. Keeping things simple and cheap often asks for quite some ingenuity.
Using the film transport as shutter (transporting the film behind the lens, keeping it there for exposure, transporting it further), will not work. The two transport action will blurr the exposure. Coping with that means efforts not related to the kind of project.
