In the first place, your DQ was already asked by Elendil’s Heir.
In the second place, the original Wonder Girl was NOT Donna Troy. Wonder Girl first appeared in Wonder Woman comics in a short series of “Impossible” stories, which not only featured Wonder Woman as a Girl, but teamed her up with herself as an adult (Wonder Woman) and as a toddler (Wonder Tot) – all three were Wonder Woman at various points in her life, which was Impossible, not only for violating the timeline, but also because she was created as an adult out of magical clay.
When DC came up with the first Teen Titans comic, they wanted more kid sidekicks. The writers glanced at Wonder Woman, saw Wonder Girl, and either didn’t notice or ignored the discrepancy. They then had to give her a distinct secret identity, hence Donna Troy.
