The answer to that is to use the EAS scale provided in the RAE chart and convert to what ever density altitude you wish.

While your work looks ok to me, I think the original question's intent was "can we convert this data to see what the a/c would be capable of at higher altitudes" which is not answered by the math you posted. Rather, we would need to check available power at the relevant altitude.
