If you have any suggestion on a clean way to achieve the same with upstream functionality, or a way to handle this, I'm all ears.

A custom option sounds good to me. Based on the description, it seems like you had to detect duplicate names. Perhaps a simpler approach would be to prepend the member index to each file unconditionally (when the new option is used).
