Cortebert 616 Street fight version

Long story short, got non working (plus a box full of pocket watch parts) Cortebert 616. Wasn't sure about the caliber but decided to get the entire box, after all it was a good price 0€.
Got home open the watch and there it was a 616 with a serial number within Rolex series (Serial numbers: 7.500.000 – 7.515.999 for the type A, B and C).
Then the amount of problems:
- Stem was broken inside the movement just at the beginning of the crown wheel. Easy fix this one.
- Balance wheel staff broken
- Balance wheel not round anymore
- Balance hair spring bended
- Second wheel not round anymore but with all the teeth
- Center wheel with 2 broken teeth
- Escape wheel not sure if it's flat
- Mainspring was full wind since 1985, so very old without service.
This is the list so far, I think more will come.
Some pictures from the movement

It used to be a pilot's watch and he dropped it from 30.000 feet

[mention]Yoda[/mention] shouldn't the wheel gears from a molnija work? I know the movement height aren't the same, the 3602 it's thinner, but removing the axis from the Molnija movement?
Newbie question

We can try, but I don't know. I have a few Molnija movements to pick from.
Russian movements are not my cup of tea anyway, might as well butcher them if it helps the 616.

I haven't access to the link, but it is good enough for me to know.
If I am not very much mistaken, then the wheels should be the same and then they can be riveted to the arbors in the 616 in case arbors are different.
