AWS::Organizations::OU should have a "parent" attribute that could be !Ref myOtherOU and not necessarily the root OU.
Then we can deploy this with StackSets... and include another StackSet in it... and hey presto....
...SkyNet.
yea agreed @rhboyd it should allow for either. I may have not worded that correctly.
From the documentation the ParentId can be either:
Root: a string that begins with "r-" followed by from 4 to 32 lower-case letters or digits.
Organizational unit (OU): a string that begins with "ou-" followed by from 4 to 32 lower-case letters or digits (the ID of the root that the OU is in) followed by a second "-" dash and from 8 to 32 additional lower-case letters or digits.
