You're making a massive jump in assumption that this is even remotely viable behavior in the face of pic related. The amount of time that it takes to get correspondence going (with or without having to track people down first) with the possibility that they'll say no can't beat, well, again, pic related. It's basic human decency to not claim others work as your own, it's a bit of a stretch to think this also includes asking permission to not claim work as your own, unless it's for profit.
With everything said, it is a bit odd to use fan art in place for reference to official characters. Unless there's details in the cosplay straight lifted from the fan art over the source character, using fan work can't ever beat official promotional material, unless the official stuff doesn't exist in any meaningful way (ie, early 2000s resolutions and compression).
