No direct solution for you but 

  a) you can probably seed the standard library RNGs as well (which may just
     need a helper function) 

  b) you can look at the very nice sample() function contributed to
     RcppArmadillo and see if you can cook something similar up for
     RcppEigen.

There are posts on the Rcpp Gallery about b).
