I am torn on intergender, I don't want it to be a thing but in a mixed tag it is stupid that when one person tags the other person basically gets a free tag. Removes most of the psychology from the match and reduces it to a hot-tag special. Rhea and Shayna could be believable, there are maybe a few others.
My only issue with the quick turn instead of a build is that I assume there will be the Saudi show, Elimination Chamber and Fastlane before WM, so what could be a great WM match for both may be stale. This is of course my main gripe with everything about the current product and a big reason NXT and only doing Takeover ~4 times a year is so good. AEW could also reach that level if they get rid of all the crap filler they have.
