As
Eliora pointed out, you've got the meanings wrong.
I don't like the combos -
Kerensa Sophia runs together, and
Olivia Athena clashes.
Sophia Kerensa and
Olivia Theodora would work better.
Kerensa and
Athena would be okay as sisters or twins, and so would
Olivia and
Sophia, but the two sets are so different that they clash when put together.
Kerensa and
Athena are too unusual-funky, and
Olivia and
Sophia are too classic-trendy.
