Thank you for the comment!
I don’t have contact with the translators as I am working as a freelancer at a company which records the audio. However, I did find a great workaround.
I import the MOTN files to a Final Cut Pro Project, then fix the timing with the time remapping tools in FCP. Then I edit the original MOTN files and change the text to the right language. The only problem with this is that sometimes you do get some loss of framerate. In a new project I solved it by making the project in high framerate in advance (50 fps). that way even if some language is 2X slower the framerate stays correct.
