If we are to attempt to go it on our current finances (which I have no problem with), I think it would be best phrased in a way to minimize (a) moral concerns, which Becky would clearly disagree with (EAT THE RICH), and (b) implications that we don't think she could safely get the job done (that is, that we won't get caught). Perhaps saying that we're pretty sure we can get by with what we have but will revisit the possibility later if something goes badly wrong would be best.
