Italian-style Iron Duke refits were possible but unnecessary

Could the Iron Duke-class battleships have received Italian-style reconstructions?

Yes technically, but Britain had newer and better ships, so the expense and yard time lacked the justification that Italy faced.

An Italian-style reconstruction of the Iron Duke class was technically possible if Britain accepted the cost and yard commitment. Italy rebuilt older battleships because limited money and industrial capacity made entirely new replacements harder to obtain. Britain already possessed newer, larger, and more capable ships on which to concentrate its resources. The proposal therefore lacked a compelling operational reason even though naval architects could have carried it out.
