I believe I was the first person who brought up this possibility a couple months back.
However as another pointed out to me, Kog'Maw joined the League BEFORE Kassadin's Daughter was lost to the void. However, the function of time and reality is probably nonexistant or very distorted in the Void.
Also, the lore stats Kog is male but.... the void is messed up so yeah....
Kog'Maw is very childish and young in nature, and we can thus assume Kassadin's Daughter was too.
It is an unconfirmed albeit possible possibility.
