Seems logical, but here's why I don't think its possible. (Spoilers as in the topic)
The sages in the temples were originally in the temples praying to the Gods so the Master Sword could keep its power. When Gannondorf came a took their souls away, they were essentially killed (and this supposedly happened before Hyrule was flooded), so therefore that boy of the kokiri could not of lived to evolve into Koroks (read Makar), he simply didn't exist anymore. Makar could be a reincarnation (which I believe is stated in the game in some form or another), but he is not the directly evolved Kokiri.
