Breakdown software RAID0

I have a 5 drive RAID 0 array of non-important data (it’s not a big deal if they are corrupted/lost, but I would rather not).

I want to destroy my RAID 0 drive by drive to then format them into RAID 0 btrfs by copying data one drive after the other.

Is there a way to do that on mdadm, moving stripes of a drive on others and then remove this drive from the array?
