Isn't it possible to make an image using light, but by computing the "real" image from the interference pattern (of a single non-repeating atom/structure)? And if there is more than one solution, then perhaps by using images from multiple angles, or with different wavelengths?

Isn't that basically what X-ray crystallography is (taking the liberty to include X-rays as "light")? Though with the (significant) restriction that it only works for repeating crystal structures, not unique individual targets...

Yes, so my question is if we can do it also on individual targets.

Ah, yes, sorry, I missed your "of a single non-repeating atom" :-)

I'm also curious -- but I wonder, would this allow for imaging anything that a scanning electron microscope can't?

Xrays are human-invisible light, part of the EM spectrum. No liberty needed.
