Oh, that is great!  Thank you so much.  This is gonna be great!

The feature is already available! Example:

\version "2.10.0"
#(define base-tempo 100)
\score{
\relative c'{
\set Score.tempoWholesPerMinute = #(ly:make-moment base-tempo 4)
c d e f
\set Score.tempoWholesPerMinute = #(ly:make-moment (/ (* base-tempo 3) 4) 4)
c d e f
}
\midi{}
}

An extra advantage of this solution in this specific application is that it
doesn't result in new printed metronome marks.
