[Space] Terraformed Venus as a setting

So let's say you left most of Venus alone, merely placed a solar shade, cleaned up the atmosphere to make it breathable, added a bunch of water, but left rotation and orbit and everything else the same. You wouldn't get the "We didn't know it wasn't Earth!" that the OP wanted, but I don't mind. I like it being alien and strange.

What would you get? Is it workable? How stable is it? Could it be shirtsleeves weather?

If you could fix the serious greenhouse problem Venus has, it would probably feel like some of the hotter periods of Earth's past. The only problems would be terrible conditions for farming, and the lack of a magnetic field being bad for forming an ozone layer. If you could artificially generate one to keep the upper atmosphere stable, it would just be a hot Earth. No volcanos, though. Venus' period of hyper volcanism went on a lot longer than any volcanic period Earth has experienced.
