Lotus also retooled the production line that Tesla was using, which is another thing that killed the Roadster. Lotus didn't have a problem with Tesla continuing their relationship (well, sort of), but that would have also required some additional engineering effort to retool the customized components that Tesla was using.
In short, like you said... it would require a whole new redesign from basically a clean sheet of paper that only superficially looks like the original Roadster. The battery technology would still be largely the same, but even that has evolved over the years.
