Definitely. The concept of Regulus Black reborn as Harry Potter allows for a lot of creativity in fanfiction. Writers can explore how Regulus' memories and motives from his previous life would impact his new life as Harry. They could also delve into how he might deal with the challenges that Harry faced in the original story in a completely new way. Maybe he would use his knowledge of the Death Eaters to fight Voldemort more effectively or have different relationships with his friends at Hogwarts. It's a really interesting premise that has led to some great fanfiction works.
Fanfiction about these three can take many forms. For example, there could be time - travel fics where Harry goes back in time and meets Regulus and Sirius when they were younger. This could lead to all sorts of interesting plot twists, like Harry trying to prevent Regulus from joining the Death Eaters in the first place. Or it could be a fic where Sirius survives and he and Harry explore the secrets of the Black family together, including things that Regulus left behind. There are also fics that focus on the emotional bonds between the characters, showing how the different personalities of Regulus, Sirius, and Harry interact and influence each other.
One common plot point is how Regulus adjusts to being Harry. Since he has his own memories and personality, it's interesting to see how he navigates the life of a young wizard in Hogwarts.
It's popular because it combines two very interesting characters. Harry is the main hero of the series, and Regulus is a mysterious figure with a complex backstory. Writers can explore what could have happened if they had interacted more directly.

Yes, there are likely some fanfictions out there with this concept.
