I wanted to know if these (3D) would fit in with 2d pixel art sprites?
do you think that this is a good idea?

In my opinion, no. A combination of styles does not work, especially in these cases, it might work in more smaller roles. It won't look nice, it would look strange, as if you're trying to hard to impress.
Only if everything is 3D rendered, it would make sense. Also, I suggest using fully nicely rendered models rather than the low-poly stuff that you usually use in a 3D game. Since it will be an image, it can be prerendered. i.e. the Donkey Kong Country trilogy on the SNES uses prerendered stuff as well. Just keep it consistent.
So in other words to answer your original question: Better don't combine pixel art and 3D art.
hear me out, if i can put a normal rpg character in a vast world of 3d then isn't there a chance for success?

i will make a screen shot of the game with a 2d character in a 3d world and then you can make your final critique.
Yea if you can make it look good then more power to ya
