Paul would know better, but I think that's unlikely. In fact, the gridBase package allows you to do use grid (and hence lattice) functions to add to a base plot, as well as (I didn't realize this before) the other way round. The only caveat is that resizing the device may mess things up.

You may have to be careful with new devices. Your example pasted on a fresh session (tested only on r-devel) starts a new page for the boxplot since it thinks that new=TRUE doesn't make sense (because there's no 'old' plot yet).
