When I say “Yes, it could probably be done” it’s because anything can be done given enough time.
In this case, if you want ACF to do it you’ll need to hack the ACF files. Exactly how, I wouldn’t know. And there is a difference between possible and practical.
I would suggest that instead of cloning the repeater you create a reasonable number of nested repeaters and clone the individual fields into the repeater. You can always and more nested repeaters later.
