The energy cost of air conditioning everything down by 450 degrees is going to be a bit of an obstacle

  Not in the upper atmosphere, where temperatures and atmospheric densities are close to Earth-normal. I think living in zeppelin cities would be logistically difficult for other reasons, but as long as you don't need to go down to the surface you don't need extreme cooling systems. If you did want people to be able to live on the surface it is kind of an interesting question how you'd manage it. Presumably there'd be ample wind energy available if you can just build a wind turbine that doesn't melt in that environment. Either way I'd rather go to Mars.

    Keeping things aloft is costly too! But the solar radiation should be favourable there, there might be a solution where you have a solar powered aircraft that always stays on the illuminated side of the planet.

      Venus has very strong winds even at high altitude. I’m not sure that staying on the sunlit side is technically feasible.

Yikes. How are we supposed to construct the floating cities? Mining Venus is out of the question with non sci-fi tech, even if all we wanted was to make, say, concrete. If something happens to the floating cities, the "fall" would be a horrendous fate. Temperature isn't "nice", would still be around 160F high up. Importing materials... at that point why not just make space stations? No water.

  An enclosed bubble of Earth atmosphere would literally float in Venus's atmosphere with about 6x as much lifting force as hydrogen has in Earth atmosphere or 10x as much as helium. As long as you can breathe, you don't fall (though "sink" is probably a better word for it than "fall").

  How feasible is to push few small metal rich asteroids towards Venus?

Bad idea. That's where they crashed the protomolocule, remember?
