Some booster battery options
Prius subpacks in 50V modules could run the converters for about 45-60 minutes continously. but will need BCM type monitoring and control.
The ultamate battery solution for the Insight would be a light weight 144V pack of Lithium or other high power to weight batteries, with 20+ usable AH capacity.Like many things in live the good stuff cost too much.
