Is there any way to avoid this to allow for thin wrappers à la do_work_ptr?

Have a look at the Ref class:

Your function should look like this then
void do_work(Eigen::Ref<Eigen::MatrixXd> mat) {
  // remaining code stays the same

You can then pass MatrixXd, Maps and Blocks with very minor overhead to your function.
