I assume, once you have allmost self replicating robots, who can do mining asteroids and building factories to build more of them and mine more and build more .. you would not need ten of thousands of years. Maybe even only some decades.

Maybe this is what Factorio has been preparing me for all this time! https://en.m.wikipedia.org/wiki/Factorio

Just make sure that you have not invented Alastair Reynolds' "greenflies".

I figured tens of thousands of years mostly for the crust reprocessing on Venus itself, for the asteroids to coalesce into a big hot blob, and for the moon blob to cool down.
Then, when Venus is spinning fast enough, collide the asteroids together to give Venus a moon and tides.
While all that is going on, use some sort of huge electromagnet to spin Venus' internal heavy core to provide a strong magnetic field to deflect nasty stuff from the Sun and elsewhere.
Also build a shield to stop all sunlight reaching Venus, thus freezing the atmosphere onto the surface. That makes reprocessing the crust into something Earth-like much easier.
Comets could then be used to provide oceans.
Shouldn't take more than a few tens of thousands of years! Seems like something a few humans, downloaded into robots, could do.
Mars would remain a scientific research station like Antarctica, assuming that life is found there. I'd treat Europa and anywhere else with life the same way.
