Yes, but the point is if they try hard and give enjoyable results, I'd be happy. Though, I wouldn't really compare animation owned by an entertainment mega-conglomerate to Henson, even when the company was really big in the 80's.You're saying "you can always make another Bugs Bunny cartoon without any of the animators or Mel Blanc" but to me that's like saying you can always make another Muppet movie without Jim Henson. As we've seen in the '90s, that's clearly not so easy.
Newer attempts at doing Looney Tunes have never been as good as the originals. The Looney Tunes stayed popular because it was still possible for a long time to see the original cartoons like the "Duck Season/Rabbit Season" bits on TV. Definitely not because of the newer projects which are barely remembered once they're done.
The problem is that we just can't get the same look and feel as the classics, but that also doesn't mean we shouldn't try. Look at how Big Tiny Toons was... and Animaniacs. Sure they ticked off a bunch of purists, but they were perfectly good forgeries of the classic characters in TV animation form. At least 4 characters on Animaniacs were revisionist history (the three warners and Slappy Squirrel), the imaginary lost and obscure Looney Toons. Tiny Toons was the next generation Looney Tunes that had Bugs and Daffy right there with them. And let's not forget Taz-Mania, Sylvester and Tweety Mysteries, and the woefully underrated Duck Dodgers. They kept the spirit of the old cartoons, but managed to pull a new twist on them, perfectly fitting into character. Even some of the newer shorts, while not as entertaining and great or memorable as they older ones (of course, a lot of their 1960's Friz Freeling ones weren't so hot either), at least TRY.
As opposed to Baby Looney Tunes or Loonatics Unleashed. Shows that the demographic was in mind the whole time, and the classic elements were thrown out the window in favor of marketing, merchandise, and other stuff that DIDN'T even happen because no one liked them... well, Baby looney Tunes had a mildly successful line of baby products, the obviously toyetic Loonatics didn't even garner a fast food promotion, much less the action figure line they CLEARLY wanted.
Perhaps the best example of my point is Tom and Jerry Tales... sure, it had Korean animation and Canadian voice actors... but even when Hanna and Barbera (or at least MGM) were in charge, they could not make anything close to the original theatrical Tom and Jerry shorts... Not the Gene Dietch ones not the Chuck Jones ones, ESPECIALLY not the Filmation ones.. not even the Tom and Jerry show they made themselves.... but Tom and Jerry Tales felt like the old shorts (with certain exceptions, and adding Droopy to the cast for no reason... but it at least felt like Droopy)... sure, it wasn't hand animated and shown theatrically, any updates actually helped the new series along... and the only major change to the characters was Mammy Two Shows was replaced by a bungling obese white female. And I'm not a fan of overly PC things, but there's no way Mammy would fly these days.
Seriously, even with that terrible theatrical animated movie (We've got to have...MONEY. Yeah, too bad you didn't make any by copying Disney) with them as executive producers... Tom and Jerry tales was the best television version of the characters. Too bad WB wanted the heck out of not-DTV movie animation, or we would have had that around a good long time.
So when it all comes down to that, you CAN make a new project that's good, just not as good, as the original if you keep the spirit and have passion filled talents behind it. But you can also have a dog mess if you just hire a bunch of hacks to pull something out of their butts to make money on T-Shirts before putting something in mothballs.
That said, the OTHER way around is even if you have the same people involved, you STILL can't recapture that magic. Look at Star Wars for example. Episode 3 was very good, but the others were missing so much.
