I'm not entirely sure I understand what you want, but I'm taking a stab 
at it.  Here's an example of how to use the same notes in different 
transpositions.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\version "2.11.65"

notes =  { c d e f }

trumpetOne = \transpose c d' { \notes }
trumpetTwo = \transpose c g, { \trumpetOne }

\score {
  \new Staff <<
    \key d \major
    \context Voice = "upper" { \voiceOne \relative c' { \trumpetOne } }
    \context Voice = "lower" { \voiceTwo \relative c { \trumpetTwo } }
  >>
  \layout {}
}

%%%%%%%%%%%%%%%%%%%%%

HTH,

Jon
