Okay, so, in what constitutes "investigative journalism" around here, I did some googling. What I found is that ... I'm not very good at googling.
But, okay, the Space Jam site has a PDF "Activity Book" and Penelope's kind of in it; her silhouette is on the back of the "cut out this mask" page along with most of the rest of the team, but she's never actually mentioned anywhere in the book, or seen anywhere else. The book does feature a short team roster, but it only mentions 10 of 18 characters, and leaves out characters like freaking Daffy Duck and Sylvester, so that's a wash. It also features two pages of cut out "trading cards" which, with 9 per page, would include all 18, but one card is deleted to explain what a trading card is, and another is used to list the Goon Squad. Marvin the Martian also didn't get a card (he also doesn't actually show up in the trailers, outside his helmet), but he does appear throughout the activity book.
While we're talking about those trading cards, they do give jersey numbers; most of the characters are the same, but there are some differences. Yosemite Sam's number 6 was changed, as 6 is Lebron's number; Sam inherited Bill Murray's 22. In what may just need a correction, Tweety Bird is 1/3; about half my sources said Tweety was 1/2 and about a third said it was 1/3 for the original movie, so I went with 1/2, but I could have got that wrong (and, no, I didn't actually go through the movie looking for numbers, I just trusted IMDB on that one). Speedy Gonzalez is .25; I don't know if that was his number in the original movie or they finally actually gave him one. The cards list the Road Runner as 5 and Lola as 11, as compared to 7 and 10 as listed above; I don't know if they were changed arbitrarily, I just got them wrong, or what, though I will say Road Runner as lucky number 7 compared to Wile E. Coyote's unlucky number 13 made sense to me. Gossamer and Granny are 00 (appropriately, all the MonStars' number) and 88, respectively.
Also, I want to clear up that Pepe was never meant to be a part of the team in A New Legacy; every description of the deleted scene sounds like they deliberately chose not to recruit him (so he was "canceled" even before he was cut); the only reason they even were talking with him is because they were looking for Lola, and Penelope had told them Pepe knew where she was.
This could be another explanation for why both Marvin and Penelope are absent from game and team scenes; they may not be part of the team. This is kind of a "good news/bad news" situation; good news, they actually have a bigger role to play than just benchwarmers, but, bad news, they're not on the team. They put'em in uniform for marketing, but that's it. I mean, the first movie had cameos of characters not on the team (besides Witch Hazel as a cheerleader and Marvin himself as the ref, the mice Hubie and Bertie were the game's announcers, and of course multiple cuts to crowd shots which were just mass cameos, which is where Penelope herself appeared), and it makes sense that they'd meet characters who weren't actually part of the team this time around, as well. As in this movie, they're using the crowd to cameo ... A Clockwork Orange, for some reason (if there's one movie kids love more than Pulp Fiction, it's A Clockwork Orange!), the actual Looney Tunes cameos would have to be before the game. There's also plenty of evidence that Marvin's green space dog, K9, will appear exactly like this. My guess is they apparently steal Marvin's base, so he's actually kind of antagonistic, while Penelope helps them recruit Lola, but otherwise, being a French cat, doesn't have much interest in playing basketball.
Of course, the "black paw" pointed out in the above thread is definitely interesting; as Daffy Duck points out, creating a CGI character is kind of expensive. If they already created a CGI model of the character, they'd use that thing, if only because they already spent the money and took the time.
Anyway, here's the mysterious black paw if you haven't seen it.
