You can reset the position in the measure with
\set Score.measurePosition = #(ly:make-moment 0 2)

But (if I understand what you really want) it might be better to separate the
measure length from the printed time signature (which you really intend to be
more of a mensuration?).  You can do that by setting measureLength and
timeSignatureFraction separately, or by overriding the time signature's stencil.
 All three possibilities below.  Hope this helps--
