One wonders if Venus will change dramatically as the sun cools (well, of course it will) over the next billlion or two years and become much more amenable to life. I mean we know the earth was a red hot ball of lava at one time.

The sun will expand to Red giant stage before cooling. The result for the terrestrial planets, especially Venus will be destruction. Even if it's core remains extant it's atmosphere will be boiled off into space. Along with Earths and Mars etc. So no. It will not become amenable to life after the sun passes thru it's red giant stage and starts to become a white dwarf.
