Interestingly someone at ESA implies that this would have been possible in this Twitter thread but I don’t think it is. As I understand it the best case delta-V of comet interceptor from L2 is around 3 km/s. If that was all used as a prograde, in-plane impulse it wouldn’t be enough to raise the aphelion to 2au (the Earth’s velocity around the Sun is around 30 km/s).
