Changing Asteroid Orbit (Planet vs Asteroid)

I do hope that we end up with far larger numbers of smaller, less damaging, easier to move asteroids rather than the current system where the smallest body is a moon with a fair bit of economic value and 3 halleys required. It's all kinda up in the air as to what uber's stance on asteroids and belts are (do I remember them saying asteroid belts will just be lots of small planetoids on the same orbit, as in manually placed in system manager?) and whether we're going to have tiny, non spherical asteroids that maybe only require one or two halleys to move at release. This would A: make you more likely to use moons as platforms to stage bombardment and invasion rather than as KEWs (as you have other, cheaper but less powerful KEWs available) and B: make the awesome factor even greater when a full sized moon or planet was used as a weapon.

EDIT: Sorry for blocky post and dense prose.

can we move to this conversation to the topic of moving planets?

it the case of planet-planet battleship crossing scenario. I really don't think putting the planet in orbit of the other is necessary. if the planet is in a similar enough orbit with the sun as the other, the two should cross from time to time and be close enough to one another to be able to fire at one another.

now it would be stupid that in this case you not be able to fire at one another because the mechanic isn't "activated" because said mechanic specifically requires the planet be in orbit around the target body.

I'd like to be reassured on whether this will simply be a question of proximity or not.

The conversation already was on topic, to not discuss the use of planets as KEWs in this discussion would be absurd and lax seeing how intrinsically linked to changing their orbit it is.

Annnnyways, I'm pretty sure it's been strongly implied (granted not confirmed) by uber that changing orbits will be dynamic, in that you can change the orbit as you like not just give binary commands of - orbit this planet or that planet. This means you can presumably also move a colonised moon AWAY from a hostile planet.
The idea of being able to fire/launch units during the points in the orbit when two bodies are closest together (is that a transit?) was definitely supported by devs in a livestream earlier in development, hopefully that's still in.
