The very best suggestion in my view was: Make it an olympic event. But, as we all know it's not going to happen. Unless some industry tycoon or IOC member was a huge pool fan and promoted this idea.
Another way would only be to make pool interesting for the masses - like the Mosconi Cup. The problem with that is, however, that the way quite a few players behave there is not attractive for tv stations. F*bombs and rude behavior just are not their kind of idea. Plus, the MC would have to be an all-nations contest.
The McD idea is not bad. However, PPV is not really too attractive - at least not over here in Europe and if it's not soccer or Formula 1 - no chance. I don't think you would get so many more people to sign up for PPV even if that McD thing would happen. If you would put up prizes instead, like pool cues, pool gloves, ball sets, a Diamond table for first prize and so on - this might just be a little more attractive. But I believe you would have to provide all those prizes to McD and getting any money out of their meals would be a pipe dream. They might even ask you to bring some extra money. At least until you finally established pool as a sought-after recreational sport. Which would take quite a while.
Another great thing would be to have background pool on the tv sets in McD restaurants. Like the famous Chris Manning runout. Spectacular Efren magic. And so on. But you would probably have to pay McD for that - they currently show terrible hip-hop-pop-whatever instead.
If you, RKC, have a buddy owning 150 stores, things might be slightly different. That man with a love for pool might do something. But I seriously doubt that a regular McD CEO would show much interest.
All you could hope for is some Warren Buffet-style person with a love for pool started to get pool into tv by staging a world championship or something. A one-time investment wouldn't help unless you set the stage for further interest. And that would mean to get pool back into ESPN, Eurosport or other tv channels. Like snooker. Once it's there for more than a single event, it would take off.
Finding the person to get it in there is the tough part, though.
Off topic: The GI crime thing in Europe is not true. Sure, there were some cases publicized here many years ago and they made the big news. It was not a case of bad GI's committing horrible crimes, though. Rather, horrible crimes are still relatively rare compared to the US over here. Very little gun violence, not a lot of rape-murders and so on. So those cases still make the news over here, occasionally. Yes, there is regular crime like husbands murdering their wives and so on, but the really spectacular bloody things are still rarer than they are in the US. And those cases almost always make the news, no matter who the perpetrator was. I haven't heard of a GI case in years now but then I don't follow those kinds of news a lot. The "Yellow Press" mostly reports on that kind of thing. But there is some crime in there always. 90% of the stories in those papers is crap anyhow - sort of like the National Enquirer.
On tv, only spectacular crime gets coverage.
