Thank you! I think you could, but it's kind of a gray area. My reasoning was that because Interstitial already tells you to think about your links a lot and make links freely, providing this as a catalyst for doing that felt like enough. It definitely feels like a spot where it's a good idea to roll for a link. I didn't want to prescribe a specific type of link for it and felt like giving a link without rolling was too much of an added benefit for something that was already getting this character out of hot water.
It's a little different from Not My Strong Suit because I feel like the situation that move speaks to is a lot more clear-cut, and the benefit it gives is more of a perk to reward another character for engaging with yours and not an immediate strong save on your character.
....But also, Interstitial is not balanced so go with whatever your heart feels is right for your idea imo.
