Homebrew Is swapping/inserting new models in a 3DS game theoretically possible?

[JoeStronger]

I recently got my hands on Dragon Quest 8 for 3DS, and I was a big fan of the Restoration Project on this very site. But those weren't really "model swaps", just seemed like a change of textures.

I was kind of interested in the possibility of putting the old Super High Tension model in for the hero in the 3DS version, I recently ripped the model from the PS2 version and I'm trying to recreate it to the specifications of the hero's 3DS model. But after scanning through the entire thread, I found out that importing any sort of new model is impossible.

Is it actually impossible, or is it only because no one's written a program that could do it? Cause if it's theoretically possible (and likely) then I'd rather try to make it, even if it's only just for Dragon Quest 8 on 3DS.

I realize that "writing a program" is no small task, but I'm up to it. I just want to know if it's possible.

If you can edit the game (and if you are running a texture mod then you have the abilities to do that) then you can edit the model too. How easy it will be to remake another system's model here is a different matter entirely -- aside from potentially having to figure out the 3ds format, the ps2 format and dealing with any restrictions the 3ds has as far as polygon budget, texture types and such like you would still have to make a 3d editor which is a fairly annoying task compared to 2d efforts. If you want a starting goal then might be worth making a 3d model viewer, or twisting an existing 3d viewer to your purposes.

When people were telling you impossible they were probably thinking you wanted to rip the ps2 version, feed it to a program and have it spit out a nice 3ds compatible version you could drop in.
