I ADORE both
Eve and
Zoe (specially with the pronunciation you're using, though I'd spell it with an accent: Zoé, as in French, or Zoè, as in Catalan), but not together. They'd make a wonderful sib/twin set, though!
I love
Ada, too, and it's my 2nd/3rd favourite name right now with the Catalan pronunciation,
AH-duh.
I also like
Asher -
Asher Michael is a nice combo-, but the others are nms.
Mara does sound and look good, imo, but the meaning is too much for me.
