Often, there could be a plotline about how his relationships change. For instance, his friends might be distrustful or scared of him at first. And he has to work hard to prove that he is still the same Edward on the inside. Another plotline might involve him having new and strange powers as a homunculus, and he has to learn to control them. Maybe he uses these powers to fight against other homunculi who are causing trouble in the world of the fanfiction.
In fanfiction, the possibilities are nearly endless. Regarding Edward Elric becoming a homunculus, it could be a very interesting concept. If he were to become one, it would completely change his relationship with other characters. For example, his brother Alphonse might react in a very different way. Also, Edward's own view of himself and his abilities would be transformed. His struggle with his new form, if it were to happen, could be a central theme in the fanfiction. Maybe he would try to find a way to reverse the process, or perhaps he would embrace his new existence as a homunculus. It all depends on the creativity of the fanfiction author.
In fanfiction where Edward Elric becomes a Homunculus, his appearance would likely change. He might have the characteristic red eyes of a Homunculus. His physical abilities would be enhanced, but at the cost of his humanity. He'd be more connected to the Homunculus' plans and goals, perhaps being forced to work against his former comrades. However, he could also use his new position to try and undermine the Homunculus from within, but it would be a difficult and dangerous path to take.
One common theme is the exploration of different types of love. There's often a mix of romantic love, friendship - like love, and loyalty among the characters in the harem. Another theme is the growth of Edward as a character as he deals with multiple relationships.
