I don't see any particular reason that it wouldn't work cleanly.

Another option, if you're using the development 1.1 releases, might be to
use a PostingSource which normally returns all documents (with a weight of
zero), but which you can make jump to the end when desired.  Then, AND that
with the query.  This approach would allow you to obtain the results which
had been calculated at the time you aborted.
