Recovering long lost Grovyle

10 years ago, my parents bought me Pokemon Alpha Sapphire as a gift, my first Pokemon game. I spent a decent amount of time playing it, and although I never got up to Mauville City, I enjoyed the game a lot. My Grovyle meant a lot to me sentimentally, and even today it still does. However, a few years ago I sold my copy of the game, and never made a backup of the save, losing it forever. Is there any way whatsoever that I could bring him back, 10 years later? Any homebrew trickery or save editing that could bring my beloved boy home?
