Not sure if you've seen this
With an emphasis on lightness, Project V previews a compact electric sports car that would sell aside its signature Seven.

Similar concept. Basically use a small battery (55kwh), ambitious target of <3000lbs with 200 miles of range. Which i think might be enough for an around-town roadster. I'm excited for smaller/lighter EVs and sports cars/sedans.
I don't think we're far off from this becoming a reality. If you think about it...BMW already did this in 2018. The i3 (while flawed in many many ways) was 3000lbs with a 40kwh battery and 160 miles of range. With 10 years of battery technology improvements, I suspect someone like Lucid could do a lot better
