No.  You propose replacing (cons 3 4) as a time signature designation
with (cons 3 (ly:make-duration 2)).  You have failed to give any
indication of what you want to see (cons 8 20) replaced with.

LilyPond does not have something like a 1/20th duration.  Regarding
durations, what occurs inside of \tuplet 5/4 and \tuplet 10/8 is
completely indistinguishable: "tupletism" is not a part of durations.

So I repeat: what duration in LilyPond do you want to use to represent
the denominator in 8/20 ?  1/20th here is neither a 5-tuplet nor a
10-tuplet: it represents a fraction of a whole note, not a particular of
several possible note values.

It will likely end up as (ly:make-duration 4 0 4/5) but that has no
unique printed representation different from (ly:make-duration 4), and
(ly:make-duration 4 0 4/5) and (ly:make-duration 4 0 8/10) are
absolutely indistinguishable.
