WWE may run into a problem: WRESTLEPALOOZA is actively trademarked by F1RST Wrestling.

To quote WWE's most relevant HoF'er: "And when you're a star, they let you do it."

"hey mom, tell kelly loeffler to tell trump to cancel a trademark love you" - triple h

I can see a few differing scenarios here.

WWE sends them money, a lot of money either for a one off or just to have it completely.

WWE uses the name anyway knowing they have more money and high-paid lawyers. F1RST would have to send off legal letters and maybe a lawsuit in this event because US trademarks must be defended or you risk losing them.

And the most unlikely thing, WWE changes the name of their event.
