The progressed houses are not viewed as the structure for the progressed planets. The computer calculations to get progressed planets will mathematically generate a framework with angles, but the NATAL chart angles and houses are the actual measurements of the physical place on earth at the time of birth and is the true base structure. Progressions represent the advancement of the natal planets' internal energies, the progressed chart houses are not an earth measured framework, the birth chart has already been established at birth. Progressed planets are placed outside around the framework/houses of the natal chart.

Thanks. All of that makes sense. I know where my natal houses are, but I suppose it makes more sense to get the natal chart with the progressed planets overlaid instead of the plain progressed chart. Easier to read. 

I've seen some significance assigned to the progressed Ascendant, particularly when it changes signs, but contacts from the progressed planets to it would not be particularly significant.

The progressed rising sign might be felt internally but it is not used as such over the natal framework. As far as feeling like a different person, through the years changing progressed ascendant signs and/or changing progressed Moon signs and phases can be experienced as an internal difference of expressions, behavior and feelings that are noticeably different from birth, also from progressions of the Mercury and Venus cycles, but our birth chart is our birth chart.
