Honestly, it's awful. Jaiyla and J'Lea are both random inventions that are entirely too similar to be used together. What about these?
Aelia (eye-LEE-ah) - Roman name, possibly meaning "sun"
Alaia (ul-EYE-ah) - Basque name meaning "joyful"
Ayala (eye-ah-LAH) - Hebrew name meaning "doe, gazelle"
Jalila - Arabic name meaning "important, exalted"
Jolie - French name meaning "pretty"
All of these have similar sounds to those in Jaiyla and J'Lea. If you're set on Jaiyla, spell it Jayla.
If the baby is going to have your last name as her last name, then Justice would be pretty awesome in the middle. Baby's mom would get to pass on her name in a cool, unique way. "Justice" is a very uplifting name that will serve your daughter well throughout life.

But seriously, spell it how you want, just avoid "jail."
