I don't know pedal steel guitar...
Anyway, I think that you can get (almost) the same result using string 
indications. You should enclose them inside <>, as explained in the big 
note here:
http://lilypond.org/doc/v2.14/Documentation/notation/common-notation-for-fretted-strings#string-number-indications


This is easier to write:

SixA = \markup \tiny \circle "6A"

{
  <c'\8>4
  <c'\8 e'\6 g'\5 >
  <f'\6 a'\5 c'\8>
  f'^\SixA
}

I don't know how to add the letter after the number. Maybe you have to 
use your markup workaround (you'd better use a variable).
