For a sister: Penelope, Lucy, Lydia, Nora. These share Eleanor's style and level of familiarity without rhyming or starting with the same letter.
Should a sibling name match Eleanor?

It helps but is not required. Another Greek name (like Eleanor) gets a small scoring bonus because shared roots read as deliberate, but a strong style match with Eleanor matters more either way.
How is the match score for Eleanor worked out?
