3D Universe has something over at DAZ along this line called Pose Repair... It kills the morph dials but it still won't do all of what you want. The only problem with both that app and what you propose is that it does not have an option to zero the Hip X-Y-Z nor delete the body x-y-z from a pose. You'd still get thrown back to zero using the pose after it was "repaired"

Many pose sets designed for a specific "scene" use the hip trans coordinates to move the figure relative to the scene zero [for example some pose sets were designed for use with specific sets or props]. Generally sets like this "force" the body trans to 0 and set the location via the hip. This means using the pose for something else means spending the time to zero the hip trans settings and adding the correct body coordinates.

I've actually gone as far as manually deleting the body trans manually via an editor.

Most "good" pose sets use the hip trans as the offset from "location" zero [i.e. if the pose is in relation to another item or character"] and delete the body x-y-z trans from the pose file. This allows you to set the "global" position of a character via the body trans and the character's relative location to that location via the hip trans.
