I honestly don't think the three kidnappers count as villains to begin with and Jason is canonically semi-friendly with them and has been giving them advice how to be less failboat kidnappers. They're much more likely to get into trouble and require Jason to save them from actual villains than they would realistically end up in a situation where Jason has to save one from the others.
I'd probably not write them very shippy shipfic without confirming because the prompt is incredibly vague, but it wouldn't be an unexpected request.
