I would argue against introducing this
complication.  Positioning spacer rests
differently to notes of the same duration
does not seem a good idea.  After all,
it is very easy to place the markup where
you want it by simply using two spacer notes:

foo = {
 s1
 \time 7/8 s8^"foobar" s8*6
 \time 10/8
}

Adjust the relative durations to achieve
the desired effect.
