I would just get some progressive rate springs for it. I purchased some for my 91 Jetta and it made a world of difference, no more diving and pitching through the corners and it also handles potholes without bottoming, unlike before. These are usually sold as trailer springs (buy front and rear) and certainly handle a loaded trailer better. This will give the car a whole new personality without changing the suspension geometry. If you raise the vehicle you will be opening a whole can of worms. You might find it is not the low feeling she doesn't like it's the mushy road feel of stock straight rate springs. Every car I buy now gets a set of progressive rate springs before I am satisfied with it.
P.S. All leaf spring suspensions are progressive rate by nature, hence the different feel of trucks.
