Getting Venus to spin at a comfortable rate is IMO the big sticking point: doing so would probably involve so much energy the planet would be pure lava and take millennia to cool down.

Venus turns to lava regularly, on a geologic time scale. It's why there aren't many craters on Venus.

TIL! Still, what mechanism could we use to increase its spin? If it happened to blow a big chunk of the atmosphere away I think that's a plus, no?

I'm still surprised that "total sun-shading" seems to have a consensus cooldown period of less than a decade.
