I think that would make the presentation awful for people who don't like Smash, don't get me wrong, I'd love it, but you also have to think about people who are not fans.
Imho the best way to show it off (assuming it's a totally new game) is giving it 5-8 minutes at the beginning of the presentation, then showing everything else they have, then closing with a big game that is going to have a new rep in Smash. Imho the most fitting would be Metroid Prime 4: they show 2 minutes of gameplay/CGI giving it context and stuff, then they show 2019, then the Smash logo appears and they announce Ridley/some other new character is now in Smash
