Would be cool, but SpaceX is not gone finance something like that. The next decadal survival is happing pretty soon. Unfortunately its unlike a large scale Venus mission will be picked.
That said, there very well might be a couple small and maybe one medium class missions picked. Don't think it would be a blimp, more likely an Orbiter.
Priority might end up being an lander for Europe style moon as a flagship. And further Moon and Mars exploration.
My hope honestly is that we do a serious rethink and go back to the Jupiter Icy Moons Orbiter but for Neptune or Uranus. A flagship mission, multiple launches, large nuclear reactor, massive amount of propellant, launched on specialised Starship to get there faster. With some real large radar on it, and maybe multiple smaller landers. Should be able to operate for 20-30 years in those systems.
This is how we need to think now for flagship missions.
I also hope for further study of a Dark side of the moon radio telescope built from moon resources.
