At first, it would be very tense. Sansa is a Stark and Tyrion is a Lannister, and she was forced into this marriage. But over time, they could start to understand each other. Sansa might see Tyrion's kindness beneath his Lannister exterior.
Another development could be that their wedding sparks a series of events that change the power dynamics in Westeros. The union of a Stark and a Lannister, even an unwanted one like theirs, could cause other houses to re - evaluate their alliances. Some might see it as an opportunity to ally with this new 'power couple' while others might view it as a threat and plot against them.
I think it's possible. They have a lot in common. They are both survivors in a world full of treachery. Tyrion's sense of humor and intelligence could be attractive to Sansa as she becomes more worldly. Sansa's beauty and her own form of inner strength might also draw Tyrion to her. Although their marriage was initially one of political convenience, the seeds of a real emotional connection could be sown as they interact more and more.
Tyrion and Sansa's relationship in fanfiction can vary greatly. Some fanfics depict them as allies. They both endured a lot in the show, and in fan - made stories, they could come together to seek revenge on those who wronged them. Their combined intelligence - Tyrion's wit and Sansa's growing political acumen - could make for an interesting partnership in fanfiction.
In these fanfictions, a prevalent theme is the idea of breaking free from the shackles of their past. Tyrion was always an outcast in his family, and Sansa had to endure so much abuse.

There are many fanfics out there, but it's a matter of personal taste. Some might find 'A Different Path' by [author name] to be an interesting take on a Sansa Tyrion story where pregnancy could potentially be a plot point.

One interesting plotline could be Sansa and Tyrion forming an unexpected alliance to outwit their enemies in King's Landing. They both have been used as pawns in the political games, and together they could use their wits and knowledge of the court to gain an upper hand.
Sansa is often very well - written. In fanfiction, she can be depicted as having fully embraced her power and intelligence. Her growth from a naive girl to a strong leader is further explored, especially in her interactions with Tyrion. Writers can show her using her experiences in the south to better rule the North and deal with Tyrion in a more equal and complex relationship.
Maybe the plotline focuses on the cultural differences that the OC brings to Sansa's wedding. For example, if the OC is from Dorne, they might introduce new traditions such as a different style of wedding ceremony or unique wedding gifts. This could cause some intrigue and also some conflict as the Northerners are not used to such things. Also, the OC could be a healer who discovers a plot to poison Sansa during the wedding and has to race against time to save her, all while falling in love with her charm and strength.
