Another could be Arthur traveling back in time to meet a young Merlin before he came to Camelot. This would change their initial meeting dynamic.
Another plot could involve Merlin traveling to the future. He might see a desolate Camelot, destroyed by some unknown force. Then he has to return to his own time and figure out how to prevent this dark future from happening. This would involve him using his magic in new and creative ways to influence the present to change the future.
One idea could be that Merlin has to hide his magic even on his wedding day to Arthur.

One idea could be that Merlin, Arthur, and the Smurfs team up to save their respective kingdoms from a common dark magic threat.

Another plot could involve Arthur getting lost in the Smurf village and learning their simple and happy way of life, which then influences his rule in Camelot.
One idea could be that they face challenges from the court. Some nobles might oppose their union due to Merlin's humble origins.

A third idea is that they go on a quest together as a married couple to find a magical artifact that can help protect Camelot from a new threat.
Well, perhaps Draco, in the role of Merlin, has a special connection to the magical creatures that he uses to help Harry. Harry, as Arthur, is trying to unite the different factions of the wizarding world. Draco's knowledge of magic, similar to Merlin's, allows him to create magical artifacts or spells that assist Harry in his quest for unity. And there could be a love story involved too, like Guinevere and Arthur, but in the context of the wizarding world with some other character and Harry.
One idea could be that in a moment of extreme danger, Merlin and Arthur share a kiss as a way of saying goodbye, not realizing they'll both survive.

One plot idea could be that they have to overcome the initial shock and resistance from the kingdom. Since it's an unconventional relationship in their world, they face challenges from the court, nobles, and even some of the common folk.

Another idea is that a magical curse forces them to get married to break it, and in the process, they discover their true feelings for each other.
