Maybe I do not get the full meaning of \powerChords, but all it seems to do
is print the chord name for a:1.5 as A5. What I was looking for is a way to
define that, for example, 

  a:five  -> <a e> -> A5

So it is the *input* side I'd want to change.

Together with a chordNameException

  <c g>1-\markup {"5"}

This would give me all I want to handle every fancy chord combination I can
dream.
