Definitely yes for including amateurs!! Everyone loves a Moneymaker story, it would be great for the game to give a chance for an amateur to play vs. the pros and maybe win the game, showing that in poker everyone can take a shot at pros.
But FOUR amateurs is too much IMO. Despite it may be a good amount if the dynamics were the same (making 4 teams initially, then each team would have one amateur in the same level, balancing the teams in some sense). But if the format is changed, 4 out of 16 seems too much. One or maybe two amateurs would be great.
However, maybe the most important question is not
if an amateur should play, but
what kind of amateur would be best for the game?
We have already seen games and streams with amateurs like Alexandra Botez, a chess master and streamer, or even Mr. Beast, the famous youtuber. Many of these streams were a great success. We have also seen videos and marketing campaigns with celebrities, like Neymar Jr (
pokerstars Pro), Cristiano Ronaldo, etc. This profile seems good for the entertainment: someone already well-known, but not a poker pro.
Another option is making big qualifiers online, and the winner gets a seat. It was good if everybody had equal chances of participating, even freeroll hustlers, not only people who play bigger stakes. I just don't know if it is good from a entertainment and marketing point of view for the show itself, maybe it is, give the fact that the audience is the poker community anyway.
