Anamorphic Lens Flare/Bloomstar in UE4?

In this video, a very long time ago, I made a four point bloom star in Hedgehog Engine (pay attention to the reflection in the glass):

I had intentionally made it so that the bloom was only visible in reflections, so specifics on that aren’t really important.

My goal was to mimic the lens flare in this old gem:

Try as I might, I cannot find a way to make anything like this in UE4. My current project is demands a certain washed-out late 70s/early 80s aesthetic, so I’ve got to find a way to make the brightest points of specular highlights and direct lights emit a star instead of the typical radial bloom.

In practice, I’m shooting for J.J. Abrams Star Trek Bloom, but a different shape, and not nearly as ridiculous.

Any resources or information would be MASSIVELY appreciated.
