I love Isaac too! But I feel like it's too close to Isaiah. Our kids names are already super matchy because of the "i" but I think Isaac is too much even for us lol.
I like Ivan, but would not do it with Ivy. Ditto Iris with Ivy and Idris. Same for Isaac and Isaiah. I would not do Icarus under any circumstances (tragedy befalls a young Greek boy who doesn't listen to his father's advice?).

Ian for a boy.
Ida is a great and little-used girl name that starts with "I" but it may be too close to Ivy.
I'd go with Irene or Imogene/Imogen.
ETA: I like Iris, but that makes both girls named after plants. That, on top of all four being I names is just too precious.
C'mon people : p
Probably go with Ian and Ingrid.
Iman?
