cutting it in half... would still require a long fuckin time

For example, when New Horizons launched back in 2006, it took the spacecraft 9.5 years to finally reach Pluto. Pulsar Fusion claims that it could cut that travel time in half.

Yeah, this is a looong way off from a 1G burn all the way.

edit: 4.5 years to pluto is about the equivalent of a 0.001G burn all the way using this to calculate
