I think
Persephone,
Thalia and
Jason are a great sibset. The mythology link isn't overpowering because there's a good balance between familiar yet mythological (Jason) and the unusual (Persephone), with
Thalia being the middle ground.
When making a combo of unusual/long first names I think a punchy middle name works best, this is obviously just my opinion, I really like from your list:
Persephone AlicePersephone Rose
