Ok, to get this into the ads plugin there would be a few hurdles to jump.
Firstly you’ll need some buy-in from the dev(s) that maintain the ads-plugin (i.e. someone relevant on the Discourse team, maybe @neil). This isn’t going to go anywhere unless you first have buy-in from the team.
Secondly, the development. As there seems to be collective interest, rather than me giving you a quote, maybe you can see how much this is worth to folks.
I suggest you create a PayPal pool, set a deadline, get the people on this topic to chip in, maybe pm a couple of others you might think would be interested in supporting it.
Once you get that lined you, you can then see if there’s a dev keen to do it for the amount of money you’ve raised. (maybe also re-categorise this to Marketplace at that point)
