You may not like Bolt cells. Bolt at over 3X SparkEV battery tapers DCFC to only 36 kW (0.6C) at around 50% charge, and 25 kW (0.4C) at 70%. By comparison, SparkEV charges at 48 kW (2.7C, 300% to 650% quicker) all the way to 80%, and replacing SparkEV cells with Bolt cells will result in slower charging.
In addition, Bolt is only 200 kW power (150% more than SparkEV) using 60 kWh (320% more than SparkEV). It's not clear if the output power limit is the battery or the motor, but it is possible that Bolt cells can't provide as much power as SparkEV cells. If that's the case, SparkEV with Bolt cells will result in slower acceleration.
As far as EV's go, SparkEV is truly a revolutionary car unlike anything on the market in many metrics. There's no EV that can charge as quick as SparkEV and very tall gear ratio (huge torque). It's also the most efficient production car ever created (though IoniqEV may rival it; not enough data on Ioniq, yet). It will be some time before other EV catch up to SparkEV. In that regard, it's pretty hard to make SparkEV "better" by using parts from other EV.
