It wouldn't be Aikido, though, it would be a technique used in Aikdio, without the aiki development. I know of no short way to develop those body principles. So I can teach a hip throw to almost anyone, and it'll look like you'd expect (rather Judo-ish). But to teach them to do it with aiki principles requires a foundation of exercises that develop those.I think he goes about it the wrong way. Give a MMA hard charger 20 minutes to learn an Aikido move and then see if he can drop Rokus with it.
Then you see Aikido with all the relevant back of house needed to make a move work.
So, while that'd be a valid test, it'd be testing not Aikido, but the technique.
