You can write

\makeDefaultStringTuning guitar-tuning \stringTuning <e, a, d g b e'>

already.  \T is not "more readable" but merely shorter.  It would be
possible to redefine \makeDefaultStringTuning to _optionally_ allow

\makeDefaultStringTuning guitar-tuning <e, a, d g b e'>

as well.  I don't believe in "increasing readability" by renaming
symbols into stuff that is not the same in definition and usage.
