I think you should follow the same pattern as what led you to
Sadie Fay. Pick a first name you like and a middle name with meaning.
Therefore I would suggest
Milo Pierantonio
Milo Peter Anthony (no hyphen, two middle names)
Georgia FlorenceGeorgia Colleen
My favourite name of all you've mentioned is
Phoenix. If you would ever consider this as a first name, I'd go for it!
Love it!
I also prefer
Georgina over
Georgia.
