Adult stem cells have already partially differentiated and are more properly called progenitor cells. Adding to telomere length will not reverse the partial differentiation so adult stem cells with lengthened telomeres will not act like embryonic stem cells. At best they will behave like younger adult stem cells (progenitor cells).
There are uses for progenitor cells but they are not pluripotent and there are large swaths of research into how cells differentiate and how humans and other animals develop that cannot be studied with progenitor cells.
