[R-sig-ME] hierarchical unbalanced design

I have a mixed model with timeseries of y and x for populations:
I am wondering if I can make it hierarchical by adding a random effect for year:
However the design is unbalanced: the time-series have different lengths for each population although the time-periods are overlapping in general.
Would it be meaningful to include the Year effect this way?
