I think it's a good idea to allow for several simulatenous
grids not necessarily sharing the same period. On the other
hand, the grid-id property seems a bit special-purpose to
me given that you can already put any kind of ID on any
grob using 'details. How about an interface based on
context names?

<<
  \new Staff {
    \makeGrid 4.*5/12 "down" % period as duration and grid end context
    ...
  }
  \new Staff = "down" {
    ...
  }

or

<<
  \makeGrid 4.*5/12 "up" "down"
  \new Staff = "up" ...
  \new Staff = "down" ...
>>

Best,
