Names for twin girls!?

In a story that I'm writing, one of the couples is expecting twin girls. I am stuck between Alexianna Jayden and Josselyn Tessa or Brylie Grace and Brielle Joy!!! Please help me pick names for the twins. If you have any suggestions please let me know. They must start with the same letter even though Alexianna and Josselyn doesn't. And the last name is Werkheiser. Yes, like Devon Werkheiser and he is with Demi Lovato in my story!
