What about the Terrascope [1] concept instead? Using the Earth's atmoshpere as a refractive lens. This requires a telescope of L2 rather than some 540AU away for a solar gravity lens. Not as powerful as the latter, but much more do-able just on the distance scale alone. It would essentially be an "Eath-observing" James Webb [1] https://ui.adsabs.harvard.edu/abs/2019ESS.....433310K/abstract https://ui.adsabs.harvard.edu/abs/2019ESS.....433310K/abstra...
