I like
Gia and
June, but
Gia June has the same hard J sound twice and very close together, so I wouldn't choose it. Maybe the J name should have more than 1 syllable so it flows better with the first hard J. Other possibilities with GJ:
Gia JeanetteGia JanelleGia JosephineGia JacinthGia JasmineGia JocelynGia JezebelGia Jiselle
