Simply put, let us slave overdrives to our jump drives. Use the standard 3x effect for 6x power cost it does for everything else, to get upwards of 3x the distance for 6x the charging cost.
Small ships that can't afford 6x the energy cost of a max power jump drive have shorter jumps, while larger ships that can afford the power can make longer jumps.
And while we're at it, overdrive the jump inhibitor as well to make sure it can keep up.
