Official campaigns in the shop for mod aircraft

As I don't know the full details of the campaign contract, I was wondering if this was possible.

Hypothetically if a map developer wanted to develop a campaign for the A-4 mod, would there be anything stopping them or would the fact it's not an official module prevent it from happening?

I would think you can’t make official paid DLC which requires an unofficial mod. That means essentially monetizing the mod. Which introduces all sorts of issues since these mods don’t meet the IP requirements to be a commercial product. 
Besides the fact that not enough people have the mod or want mods in general to make such a thing feasible. People can always create unofficial campaigns for the User Files sections.

Yup, that sounds like a huge legal mess.
