Well, FanFiction.net could be a place to look. Just type in 'Leon x Hunnigan' in the search bar, and it'll show you relevant stories. However, the quality can vary a great deal.

Hunnigan could be a great addition. She could provide Leon with information and support from the outside, and her presence could add some tension as she might be suspicious of Ada's motives.
