No, it's still poor grammar. You changed the sentence from an assertion about the relative ages of kotorkyle and gabrielle to an assertion about the presence of a suspicion about the relative ages of the two. The first makes an assertion about the ages, the second raises a possibility. Even if it's artistic licence, and even if it was not done for any malevolent purposes, the meaning of the sentence has still been changed, thus there has been a change, rather than a correction, in the grammar.

No, it is completely outside the boundaries of grammar. It is within editorial licence for the reader to interpret as they will. In fact, the structure of my correction not only presents a fair and clear interpretation, it also grants the reader the immediate power of recognising what is edit and what is the original statement.
To wit, the correction was helping to state what kotorkyle meant to say, even though poor grammar and eloquence prevented such communication.
