John: I would say that your proposed use of a turbo charger is its best use but personally have flown C-172s to 13,000 & C-182s to over 15000' for short periods but view 12,500 ft about the limit for sustained operation by a non-smoking pilot or passenger without Oxygen. I believe the craft you site all have service cielings in the 14000 area anyway. Beware of over-boosting as it can be hard on engines and shorten their life.
Having been in and out of Prescott AZ several times as well as high density altitude conditions in the Calif. Central Valley and those of the CA deserts I can understand your position very well.
