Only person I ever knew with the name pronounced it 'da-NA-ey'. I'd go with that, considering that she was Greek herself...
With a name with three syllables, it's not a good idea to put a name with too many syllables next to it. I'd go with
Danae Layla, 'cause
Layla is the shortest. Still, it'd be better to have a one-syllable name as a mn.
