You are missing one very important step that you should make regardless of
which approach you use:
0) Make a backup of any and all data that you don't want to lose (and check
that you can restore data from the backup while you still have the
original data.)

(Somebody else will have to answer if the above can be expected to work or
not, but I suspect that it would be easier and less errorprone to do as
follow:
1) Make backups of all data
2) Delete the old RAID array.
3) Create a new array from scratch
4) Restore data from backups)
