This pretense slowly starts to feel real as they get to know each other better, and they have to balance their real mission with their fake relationship.
Maybe a fanfiction where Buck gets injured during a mission and Caveira has to take care of him in a safe house. During this time, they have deep conversations about their pasts, their reasons for joining Rainbow Six. This could explore their characters more deeply and also lead to a romantic or at least a very strong friendship developing between them.
Their different skillsets make them an interesting pair. Buck is known for his aggression and his ability to break through barriers, while Caveira is all about stealth and interrogation. In fanfiction, this contrast can lead to a lot of conflict and then resolution as they learn to work together.

Also, a story where the nephews get to run the business for a day and end up getting into all sorts of hilarious and dangerous situations.
