Can Wonder Man still make an appearance in Infinity War?

As you may know,Simon Williams a.k.a Wonder Man was supposed to be in Guardians Of The Galaxy Vol.2 not as the hero we well know him as,but as the Tony Stark-ish personality actor he used to be.
His cameo wouldn't be very noticable as it was a scene in a cinema with six movies all starring Simon Williams. All of these movies were easter eggs to real movies that exist and are considered classic. For example:

This is a poster of Tony Stark starring Simon Williams,this is obviously an easter egg to the movie Steve Jobs.
Simon Williams is played by Nathan Fillion which makes us want to see him even more as Nathan Fillion is great at playing selfish characters just like this one.
Still fans speculate if Wonder Man will be in Infinity War but what i really want to know if the Simon Williams in the MCU is really Wonder Man. Has he gotten his super powers yet or he's just a character full of easter eggs?

I don't really see a problem with Wonder Man being in a Avengers movie since his first comic appearence was in the first Avengers comics.

I really hope Wonder Man makes an appearence in Infinity War since he's one of the strongest beings in Marvel along with Hulk and Sentry. His character design is more than it meets the eye as he has the generic superhero look with some of the most unique super powers in the comic industry.

Of course with speculations of him being in Infinity War comes the question,how will he appear in Infinity War? Will he just jump out of nowhere and help the Avengers or be recruited by Tony Stark/Steve Rogers?
In my opinion i think he should be a secret weapon of S.H.I.E.L.D.
I know that S.H.I.E.L.D in the movies is no more but c'mon...Something like S.H.I.E.L.D can never be dead,besides if Wonder Man is a secret weapon of theirs,it can give the former S.H.I.E.L.D members Hawkeye and Black Widow more than 2 important scenes in this big movie.
