In as much as you already intend to replace the furler, it would be wise to move it above deck with some extension plates and fabricate a cover for the deck opening that will limit the amount of water that can enter the anchor locker. Based on some rough calculations the anchor locker is about two cubic feet which, when filled with seawater, would arguably add roughly 128# to the bow. Drains are all well and good but if you find yourself beating into a head sea, it it unlikely that your locker could drain before being refilled by the next sea.
For the sake of the exercise, block your exisitng drain with a cork, fill the locker with water, pop the cork and time how long it takes for the locker to drain. IF your going to add another drain of the same size, cut the time in half. If, as I suspect, a full locker takes more than 4 seconds to drain, (and remember that while the bow is buried in a head sea the "drain" will actually be admitting water, not discarding it), in a heavy sea--and you will have them sooner or later--the box simply won't be able to clear before its refilled.
The added weight doesn't sound like that much but it will significantly add to the pitching moment of the yacht increasing the bow's tendancy to pound and/or "pearl". Moreover, your Widlass might be water-proof to some extent but it wasn't designed to be continuously immersed and water under pressure will, eventually, makes its way into the works.
"It is not so much for its beauty that the sea makes a claim upon men's hearts, as for that subtle something, that quality of air, that emanation from the waves, that so wonderfully renews a weary spirit."
