Is a future where wars are waged with Gundams possible?

Not that much more difficult; asteroid belts are incredibly sparse. This is because space is ridiculously, absurdly, unfathomably big.

I mean yeah but comparitively more difficult in comparison to well the rest of space.

Asteroid fields aren't even remotely as densely packed as fiction often depicts them.

Asteroids in the asteroid belt are VERY far apart.

Millions of kilometers apart.

They might have been if physics was on the side of giant bipedal complex armored weapons platforms and if nuclear bombs didn't exist. Guarantee they would be symbols of the state and not the light of hope they are often presented as in the shows.

There's high chance we will have a very Gundam-like future in a number of ways, aside for, you know, the Gundams

These things aren't a figment of Tomino's imagination. They are something an actual physicist came up with.

Except they'd be in pairs and/or maybe inside hollowed out asteroids.

Insane, humanity could have face to some crazy fascist group which could drop colonies to Earth before make a real mecha.

A large, bipedal robot represents a huge target profile. If anything, future armoured warfare will probably get lower and flatter.

So like the Sidonia

I'm no specialist but I remember reading somewhere that if we built "anime mechas" at scale, most would not even support their own weight and they could not keep their integrity.
Also, putting a live human inside a war machine is most likely not how future wars would happen. It would be remote controlled or fully autonomous, as a human body would limit the possibilities tremendously.
Finally, I don't think real life mechas would be an effective weapon.
