Purchase a changing bag, expose a few frames of film.
Put camera, and developing tank in changing bag.
Cut film, and install exposed film into reel, and secure tank.
Reattach film, and repeat ...

One basic comment: you'd be working at speeds where 35mm would give you no working advantage over mid- or large format. At that point you'd probably be much better off with a larger negative.
Sticking to 35mm, you could look into swapping out film as needed. Some cameras make that easier.
The classic Exaktas let you use a cassette as a take-up spool and even have a film cutter for quick daylight swaps.
The Rolleiflex SL2000F & 3003 have interchangeable film backs and you could, for example, carry 3 magazines around for -1, 0, & +1 exposed film, changing as needed.
Carry 3 bodies: your Olympus is small and the 2 extra bodies would probably still be more convenient that any 35mm sheet back.

I aware of the complexity and the required engineering...
Right now, I am trying to find little bit more about the design such as distance between the lens and the film.
If you are using an existing camera as a base, then your cut film would have to end up resting on the camera's own film guide/base anyway (unless you replace everyhing, but that requires a *great* machinist & the proper tools).
The Rolleiflex magazines I mentioned earlier could be loaded with individual cut film frames (though I'd imagine it being a PITA to do so) and have their own dark slides as well. That could be a solution for you to experiment with, though the Rolleiflex bodies (and magazines) aren't cheap.
Right now, I have no access to the camera and when I am at home I will try to slide the film through the guide. Then I will have a better idea
I presume, the film holder will be the size of a match box but slightly thinner. It should have groove for film to slide and an another for a metal slider for light seal.
Hope it won't pose any serious engineering problem...
Not to discourage you, but your plan would require:
1) Your film holder would have to be attached to the camera so no light leaks through the joins.
2) You'd need a dark slide (light seal) which is light-tight and can be removed once the film holder is in place.
3) The film would have to move forward to rest on the camera's film guides once the dark slide is removed (a good spring system).
4) The spring system would also have to keep the film perfectly flat.
5) The film holder and/or camera would have to be machined so that the dark slide can be put back in without damaging or scratching the film.
6) Probably something else important & complicated I haven't thought about
IMHO, *not* an easy thing to actually build.
There's a reason why interchangeable film magazines & cameras tend to be very expensive!
Good luck!
