Not really. I thought we're talking about a (new) tabmode entry which allows to enter fret numbers (or letters signifying frets) instead of letters signifying notenames. An example (LilyPond excerpt of a german Christmas Carol – not crazy Bach! ;-) The melody modulates temporarily form g to d major):
   
      \key g \major
      \time 4/4
      \relative c' {
      a a b cis |
      d2 a |
      b4 e d cis |
      e2 d |
      }

A hypothetical tabmode entry of the same excerpt (\3 and \2 means string number; numbers without underscore signify fret numbers (quarter notes); e.g. 2_2 stands for fret 2, half note:

      \key g \major
      \time 4/4
      { \3 2 2 \2 0 2 |
      3_2 \3 2_2 |
      \2 0 \1 0 \2 3 2 |
      \1 0_2 \2 3_2 | }

As I understand it the problem is: How to teach LilyPond how to interpret the fret numbers. The second fret on the second string could mean a "c sharp" or a "d flat". So one way could be to write something like "\accidentals cis" in front of each occurrence of "\2 2". It might be even more comfortable to be able to write something like "\mode d\major" in front of the first occurrence of "\2 2" and all the following cis-notes on any string are engraved correctly. When the melody modulates back to g-major you would have to change the mode again.

Just an idea.
