I don't think it's "wrong" if you just don't happen to be a fan of Kofi... but at the same time, for 'Craig' to think Ali is a better idea is kinda goofy.
There's a better story with Kofi than someone who just jumped from 205 Live two months ago.
A person who's won every title except THAT title, been there for years, has consistently remained popular, but has never had that big title match... this makes sense, especially for a WrestleMania feud. There's a whole backstory you can attach to it that makes sense. That's way more compelling than "wrestler gets added to the roster, beats champion in a non-title match, let's give him a match for the belt at Mania". The Ali shyt is the type of stuff they could just do on the regular TV, not the biggest show of the year.
Sure, you can say this was all happenstance, no one woulda called this for Kofi two months ago, etc... which is all true, but now that this has happened and became extremely hot, it's the way to go for WM. It's probably better than whatever else they had lined up. This wouldn't be the first time they happened to fall into something and ran with it, and it turned into something great.
