Yes and lets have a kirby game in a death space setting


Somethings just dont mix

I think having Link in Mario Kart is enough. They could add Zelda and Ganondorf next time

They could make Nintendo Kart, but probably still call it Mario Kart because that brand-name is probably too big at this point

Super Kart Bros.

It practically already is.  Last I checked...

Link

Animal Crossing Characters

Inklings

...are not Mario characters.  I honestly see Mario Kart being more like Smash in terms of characters by the next mainline release.

Can't be less like Zelda than Breath of the Wild was.

No, I don't think it would work.
Not because of something like "Ohmygod, whatthefuckisthisshit?! Zeldaracinggame! Thissucks! FuckyouNintendo, vlerheiwarhiogj. (fan meltdown)."
It's not really something that there is demand for and it would be really jarring and a hard sell.
Nintendo has a lot of franchises and characters that they can take in a lot of different genres, formats, and directions; Zelda is not one of them.
Like kirby007 said: somethings just don't mix.
As far as spinoffs go, Zelda has proven it can be very successful in hack 'n' slash with Hyrule Warriors, and I also think it could pull of an RPG very well. Albeit, I think it would be better suited in the more Western style (Elder Scrolls, Fallout, Witcher) than the Japanese style (Dragon Quest, Final Fantasy, Persona). Breath of the Wild already leans more towards that direction and that's the most financially successful and critically acclaimed Zelda game in history. But that's about it. You can't do nearly as much with Zelda as you can do with IPs and franchises with more generic, widespread, and flexible characters like Mario, DK, Kirby, Animal Crossing, or Pokemon.
I just don't think it would work. I'm not opposed to the idea. If it happens, cool, let's see how it turns out. If it doesn't, oh well. But as for it being successful and being a hit? I just can't see it.

If Zelda is going to get a really out there spin off it should be a turn based rpg or a Diablo style dungeon crawler

I have to say i think it would be cruel to make a Zelda-racer when people are clamoring for a new F-Zero, Maybe Nintendo should invest in that instead

Ewww no
