I'd say that Guinevere would have had her hands full holding her throne and keeping the kingdom safe from outside threats.

Despite being named heir by Arthur, her background means that it'd be guaranteed that there would be people who would feel that she had no right to be Queen, especially when there is really only Gaius and Merlin's word for it that Arthur chose her to succeed him. Both are commoners - a few short years of Arthur's reign will not have erased the attitude that the word of a commoner is worth much less than the word of a noble - and known to be staunch supporters of Guinevere so it would hardly be a huge stretch to imagine that they might lie about it if Arthur didn't name a successor or named somebody else.

Camelot's army was decimated. Uther lost at least half of his army searching for Morgana when she was missing, then more soldiers when Cenred and the skeleton army attacked. The Dorocha reduced Camelot's population quite significantly. Both of Morgana's conquests would have meant heavy casualties for Camelot. Same goes for the Battle of Camlann. Others were lost along the way, at various times. As of the end of the series, Camelot's army has to have been reduced to a small fraction of what it was at the end of Season Two, and I can't imagine that they have many young, able-bodied men left to draft for military service. This leaves the kingdom vulnerable to outside threats.

I doubt that Guinevere could afford to alienate those who hate and fear magic and, after the slaying of the last High Priestess of the Triple Goddess, followers of the Old Religion are unlikely to be interested in any overtures she might make and probably regard Emrys as a traitor to his own kind for devoting himself to a King who kept magic outlawed for the entirety of his reign.
