Trading Nelson's torpedoes for power and layout

Would it be worthwhile to remove Nelson's torpedoes in exchange for more propulsion capacity?

Yes; the freed weight and space could support more power and perhaps allow one main turret to move aft.

Exchanging Nelson's torpedo capability for additional machinery is judged worthwhile. The released allowance could provide more power and, if possible, move one turret aft rather than leaving all three forward. The trade would change speed, internal volume, and firing arcs within a fixed hull. It is a concise example of how one weapon can limit several other design choices.
