I'm not saying you shouldn't make a statement, i'm saying that something like this is probably not the best thing to do. Its going to be borderline impossible to avoid having your entrants miss their main matches, and I doubt many high profile players like M2K would choose to enter at the risk of getting DQed from the other events. If you want to make a statement, the first step is probably to stop supporting a TO like alex strife who has really done nothing good for PM ever. He's always had a bias towards it, not allowing it at 2013 and being extremely reluctant towards adding it last year (including not allowing teams). If you want PM to be featured more, supporting Apex is not the way to go.
Apex is a very large tournament, but not the only tournament. There are other nationals that do support PM, such as The Big House and Low Tier City, that would do much more for you as a PM player. There's no rule saying that you have to go to Apex, or that Apex is the only tournament that matters for Smash. If you want to keep our community going strong, go to those tournaments, or even host your own! There's plenty you can do to keep PM going without having to host an underground tournament at someone else's event.
