You can do that, but it might be fine to just leave them for that amount of time. Did they just finish fermenting? If it was a healthy fermentation I probably would be fine with leaving them for a month. I normally leave my beers on the yeast for a couple of weeks after the primary fermentation is finished.
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. - C. S. Lewis, English essayist & juvenile novelist (1898 - 1963)
