One way to blend them is through a time - travel plot. Bruce Banner somehow travels back in time to the era of the Marauders in the Harry Potter universe. He meets young Sirius Black or Remus Lupin. Banner's knowledge of science and his modern - day thinking could be fascinating to them. The slash could develop as a strong friendship that has undertones of more. For example, Banner and Lupin could support each other in dealing with their respective 'inner beasts' - the Hulk for Banner and the werewolf for Lupin.
A simple way is to have Bruce Banner be a Muggleborn in the Harry Potter world. This would allow for his character to be integrated into the story more easily. The slash aspect could involve a relationship with Harry Potter himself. They could bond over their shared experiences of feeling different from others. Harry as a wizard with a unique past and Banner as a scientist with a big secret (the Hulk).
To blend them well, consider their personalities. Harry is brave and determined, while Banner is intelligent and somewhat reserved. In a fanfiction, they could meet during a dangerous situation, like a dark wizard attack on a Muggle area. Banner might accidentally get involved and use his scientific skills to help, which catches Harry's attention. As for the slash part, their growing respect for each other could turn into a deeper emotional connection as they continue to face challenges together and learn more about each other's worlds.
