Re potted root system

Okay, this morning i cut down my gold leaf to dry. I had a idea i washed the roots or what part of the roots i could successfully save around 7" of root system. I replanted it in fresh soil. Will this regrow and if it does what sort of plant should i expect? I have other plants just wanted to see if this would work.

Did you leave anything green growing on the plant? If so, and you left enough to power photosynthesis, it may re-veg if left under 18-24 hours of light.
